Is 2017 Half Empty or Half Full?

Ransomware seems to be this year’s huge trend

With 2017 crossing the half way point, let's look at some technology trends thus far.
Breaches: Many personal records are half empty due to the continued rash of intrusions while the crooks are half full of our personal information along with some ransom payments. According to the Identity Theft Resource Center (ITRC), there have been 7,689 breaches since 2005 (when they started tracking) compromising – get this – 900,315,392 records. Almost 3 times the U.S. population. In 2016, 56% of all Data Breaches began with a user clicking on a phishing email. The big story for 2017 I think, is the rise of ransomware. Kaspersky reports a 250% increase in ransomware for the first few months of 2017. From WannaCry to Petya to Fusob, criminals are holding systems hostage until a ransom is paid…or not. Ransomware seems to be this year’s big trend with backups saving some from total embarrassment.

Cloud Computing: RightScale 2017 State of the Cloud Report notes that Hybrid Cloud Is the preferred enterprise strategy, with 85 percent of enterprises have a multi-cloud strategy (up from 82 percent in 2016) and Cloud Users Are Running Applications in Multiple Clouds. An interesting stat from the report says, cloud users are running applications in an average of 1.8 public clouds and 2.3 private clouds. We got hybrid cars, hybrid corn, hybrid cats and hybrid clouds but The Cloud is Still just a Datacenter Somewhere so no need to freak out. Cloud seems to be more than half full as the security and expertise challenges decline.

DNS: I’ve said it before and I’ll say it again, DNS is one of the most important components of a functioning internet. With that, it presents unique challenges to organizations. 2016 saw record-breaking DNS-based attacks and outages, which thrust DNS management into the spotlight as both a vulnerability and a critical asset. In 2016 DNS provider Dyn experienced a huge DDoS attack taking out many popular websites and internet cameras. And a new attack uncovered this year, DNSMessenger, uses DNS queries to conduct malicious PowerShell commands on compromised computers – a technique that makes the remote access trojan difficult to detect on targeted systems. The need for DNS continues to be half-full with the influx of IoT devices so it’ll continue to be a valuable target for riff-raff.

IoT: What can I say? The cup runneth over…again. Gartner has identified the Top 10 IoT technologies that should be on every organization's radar for 2017 and 2018. They include things like new security risks and challenges to the IoT devices themselves, their platforms and operating systems, their communications, and even the systems to which they're connected. Analytics to understand customer behavior, to deliver services and improve products. Device management, device processors, operating systems, platforms, standards and even the networks IoT devices use are all areas of attention. IoT is really three-quarters full both with the opportunities and potential risks. And the risks can be deadly when monitoring vital information like human vital signs.

Mobile: We are mobile, our devices are mobile and the applications we access are mobile. Mobility, in all its iterations, is a huge enabler and concern for enterprises and it'll only get worse as we start wearing our connected clothing to the office. 5G is still a couple years away but AT&T and Verizon have already lined up trials of their 5G networks for 2017. Mobile is certainly half full and there is no emptying it now.

That's what I got so far and I'm sure 2017's second half will bring more amazement, questions and wonders. We'll do our year-end reviews and predictions for 2018 as we all lament, where did the Year of the Rooster go?

There's that old notion that if you see a glass half full, you're an optimist and if you see it half empty you are a pessimist. I think you need to understand what state the glass itself was before the question. Was it empty and filled half way or was it full and poured out? There's your answer!

What is DNS?

What is the Domain Name System (DNS)?

Imagine how difficult it would be to use the Internet if you had to remember dozens of number combinations to do anything. The Domain Name System (DNS) was created in 1983 to enable humans to easily identify all the computers, services, and resources connected to the Internet by name—instead of by Internet Protocol (IP) address, an increasingly difficult-to-memorize string of information. Think of all the website domain names you know off the top of your head and how hard it would be to memorize specific IP addresses for all those domain names. Think of DNS as the Internet's phone book. A DNS server translates the domain names you type into a browser, like www.f5.com, into an IP address (104.219.105.148), which allows your device to find the resource you're looking for on the Internet.

DNS is a hierarchical distributed naming system for computers, services, or other resources connected to the Internet. It associates various information with domain names that are assigned to each of the participating DNS entries.

How DNS Works

The user types the address of the site (www.f5.com as an example) into the web browser. The browser has no clue where www.f5.com is, so it sends a request to the Local DNS Server (LDNS) to ask if it has a record for www.f5.com. If the LDNS does not have a record for that particular site, it begins a recursive search of the Internet domains to find out who owns www.f5.com.


First, the LDNS contacts one of the Root DNS Servers, and the Root Server responds by telling the LDNS to contact the .com DNS Server. The LDNS then asks the .com DNS Server if it has a record for www.f5.com, and the .com DNS Server determines the owner of www.f5.com and returns a Name Server (NS) record for f5.com. Check out the diagram below:

Next, the LDNS queries the f5.com DNS Server NS record. The f5.com DNS Server looks up the name: www.f5.com. If it finds the name, it returns an Address (A) record to the LDNS. The A record contains the name, IP address, and Time to Live (TTL). The TTL (measured in seconds) tells the LDNS how long to maintain the A record before it asks the f5.com DNS Server again.

When the LDNS receives the A record, it caches the IP address for the time specified in the TTL. Now that the LDNS had the A record for www.f5.com, it can answer future requests from its own cache rather than completing the entire recursive search again. LDNS returns the IP address of www.f5.com to the host computer, and the local browser caches the IP address on the computer for the time specified in the TTL. After all, if it can hold on to the info locally, it won't need to keep asking the LDNS.

The browser then uses the IP address to open a connection to www.f5.com:80 and sends a GET /... and the web server returns the web page response.

DNS can get a lot more complicated than what this simple example shows, but this gives you an idea of how it works.

DNS Importance

As arguably the primary technology enabling the Internet, DNS is also one of the most important components in networking infrastructure. In addition to delivering content and applications, DNS also manages a distributed and redundant architecture to ensure high availability and quality user response time—so it is critical to have an available, intelligent, secure, and scalable DNS infrastructure. If DNS fails, most web applications will fail to function properly. And DNS is a prime target for attack.

The importance of a strong DNS foundation cannot be overstated. Without one, your customers may not be able to access your content and applications when they want to—and if they can't get what they want from you, they'll likely turn elsewhere.

Growing Pains

DNS is growing especially with mobile apps and IoT devices requiring name resolution.  Add to that, organizations are experiencing rapid growth in terms of applications as well as the volume of traffic accessing those applications.

In the last five years, the volume of DNS queries on for .com and .net addresses has more than doubled. More than 10 million domain names were added to the Internet in 2016 and future growth is expected to occur at an even faster pace as more cloud, mobile and IoT implementations are deployed.

Security Issues

If DNS is the backbone of the Internet—answering all the queries and resolving all the numbers so you can find your favorite sites—it is also one of the most vulnerable points in your network. Due to the crucial role it plays, DNS is a high-value security target. DNS DDoS attacks can flood your DNS servers to the point of failure or hijack the request and redirect requests to a malicious server. To prevent this, a distributed high-performing, secure DNS architecture and DNS offload capabilities must be integrated into the network.

Generally, DNS servers and DNS cloud services can handle varying amounts of requests per second with the costs increasing as the queries-per-second increase.

To address DNS surges and DNS DDoS attacks, companies add more DNS servers, which are not really needed during normal business operations. This costly solution also often requires manual intervention for changes. In addition, traditional DNS servers require frequent maintenance and patching, primarily for new vulnerabilities.

The Traditional Solution

When looking for DNS solutions, many organizations select BIND (Berkeley Internet Naming Daemon), the Internet's original DNS resolver. Installed on approximately 80 percent of the world's DNS servers, BIND is an open-source project maintained by Internet Systems Consortium (ISC).

Despite its popularity, BIND requires significant maintenance multiple times a year primarily due to vulnerabilities, patches, and upgrades. It can be downloaded freely, but needs servers (an additional cost, including support contracts) and an operating system. In addition, BIND typically scales to only 50,000 responses per second (RPS), making it vulnerable to both legitimate and malicious DNS surges.

Lightboard Lessons: DNS Scalability & Security

The Domain Name Service (DNS) is one of the most important components in networking infrastructure, enabling users and services to access applications by translating URLs (names) into IP addresses (numbers). Because every icon and URL and all embedded content on a website requires a DNS lookup, loading complex sites necessitates hundreds of DNS queries.

DNS lookups has exploded in recent years with mobile, IoT and the applications to support the growth. It is also a vulnerable target. In my first Lightboard Lesson, I show you how to scale, secure and consolidate your DNS infrastructure.

Is 2016 Half Empty or Half Full?

Updating passwords is a huge trend in 2016

With 2016 crossing the half way point, let's take a look at some technology trends thus far.

Breaches: Well, many databases are half empty due to the continued rash of intrusions while the crooks are half full with our personal information. According to the Identity Theft Resource Center (ITRC), there have been 522 breaches thus far in 2016 exposing almost 13,000,000 records. Many are health care providers as our medical information is becoming the gold mine of stolen info. Not really surprising since the health care wearable market is set to explode in the coming years. Many of those wearables will be transmitting our health data back to providers. There were also a bunch of very recognizable names getting blasted in the media: IRS, Snapchat, Wendy’s and LinkedIn. And the best advice we got? Don’t use the same password across multiple sites. Updating passwords is a huge trend in 2016.

Cloud Computing: According to IDC, public cloud IaaS revenues are on pace to more than triple by 2020. From $12.6 billion in 2015 to $43.6 billion in 2020. The public cloud IaaS market grew 51% in 2015 but will slightly slow after 2017 as enterprises get past the wonder and move more towards cloud optimization rather than simply testing the waters. IDC also noted that four out of five IT organizations will be committed to hybrid architectures by 2018. While hybrid is the new normal remember, The Cloud is Still just a Datacenter Somewhere. Cloud seems to be more than half full and this comes at a time when ISO compliance in the cloud is becoming even more important.

DNS: I’ve said it before and I’ll say it again, DNS is one of the most important components of a functioning internet. With that, it presents unique challenges to organizations. Recently, Infoblox released its Q1 2016 Security Assessment Report and off the bat said, ‘In the first quarter of 2016, 519 files capturing DNS traffic were uploaded by 235 customers and prospects for security assessments by Infoblox. The results: 83% of all files uploaded showed evidence of suspicious activity (429 files).’ They list the specific threats from botnets to protocol anomalies to Zeus and DDoS. A 2014 vulnerability, Heartbleed, still appears around 11% of the time. DevOps is even in the DNS game. In half full news, VeriSign filed two patent applications describing the use of various DNS components to manage IoT devices. One is for systems and methods for establishing ownership and delegation of IoT devices using DNS services and the other is for systems and methods for registering, managing, and communicating with IoT devices using DNS processes. Find that half full smart mug...by name!

IoT: What can I say? The cup runneth over. Wearables are expected to close in on 215 million units shipped by 2020 with 102 million this year alone. I think that number is conservative with smart eyewear, watches and clothing grabbing consumer’s attention. Then there’s the whole realm of industrial solutions like smart tractors, HVAC systems and other sensors tied to smart offices, factories and cities. In fact, utilities are among the largest IoT spenders and will be the third-largest industry by expenditure in IoT products and services. Over $69 billion has already been spent worldwide, according to the IDC Energy Insights/Ericsson report. And we haven’t even touched on all the smart appliances, robots and media devices finding spots our homes. Get ready for Big Data regulations as more of our personal (and bodily) data gets pushed to the cloud. And we’re talking a lot of data.

Mobile: We are mobile, our devices are mobile and the applications we access are mobile. Mobility, in all its iterations, is a huge enabler and concern for enterprises and it'll only get worse as we start wearing our connected clothing to the office. The Digital Dress Code has emerged. With 5G on the way, mobile is certainly half full and there is no empting it now.

Of course, F5 has solutions to address many of these challenges whether you’re boiling over or bone dry. Our security solutions, including Silverline, can protect against malicious attacks; no matter the cloud -  private, public or hybrid - our Cloud solutions can get you there and back; BIG-IP DNS, particularly DNS Express, can handle the incredible name request boom as more ‘things’ get connected; and speaking of things, your data center will need to be agile enough to handle all the nouns requesting access; and check out how TCP Fast Open can optimize your mobile communications.

That's what I got so far and I'm sure 2016's second half will bring more amazement, questions and wonders. We'll do our year-end reviews and predictions for 2017 as we all lament, where did the Year of the Monkey go?

There's that old notion that if you see a glass half full, you're an optimist and if you see it half empty you are a pessimist. I think you need to understand what state the glass itself was before the question. Was it empty and filled half way or was it full and poured out? There's your answer!

The Dangerous Game of DNS

The Domain Name Service (DNS) is one of the most important components in networking infrastructure, enabling users and services to access applications by translating URLs (names) into IP addresses (numbers). Because every icon and URL and all embedded content on a website requires a DNS lookup, loading complex sites necessitates hundreds of DNS queries.

And because of that, DNS is a precious target and only lags behind http as the most targeted protocol.
DDoS-ing DNS is an effective way to make the service unavailable. As the flood of malicious DNS requests hit the infrastructure, the service can become unresponsive if there is not enough capacity. Organizations can add more servers or turn to their cloud-based security provider for help. One of the strategies cloud-based security providers use to shield DNS is DNS redirection. Cloud providers will divert incoming traffic to their own infrastructure, which is resilient enough to detect and absorb these attacks. The success of this strategy however depends on how well the website's original IP address can be shielded. If the bad guy can find that IP address, then they can get around the protection.

So is DNS redirection effective? Researchers decided to find out.

Scientists from KU Leuven in Belgium built a tool called CLOUDPIERCER, which automatically tries to retrieve websites' original IP address, including the use of unprotected subdomains. Almost 18,000 websites, protected by five different providers, were part to the team's DNS redirection vulnerability tests. In more than 70% of the cases, CLOUDPIERCER was able to retrieve the website's original IP address - the precise info needed to launch a successful attack.

Researchers did share their findings with those cloud-based providers and have made CLOUDPIERCER freely available for organizations to test their own DNS infrastructure.

In another DNS scam, a new version of the NewPosThings PoS (point of sale, not…) malware is using DNS rather than http/https/ftp to extract data from infected PoS terminals. This is an interesting twist since most security solutions monitor http/https traffic for suspicious activity. Anti-virus doesn’t necessarily watch DNS and admins cannot simply turn off DNS since they need it to resolve hostnames and domains. Seems like a clear shot.

The newest version of NewPoSThings is nicknamed MULTIGRAIN and it only targets (and infects) one specific type of PoS platform: The multi.exe process, specific to a popular electronic draft capture software package. If the multi.exe process is not found the malware moves on. Once inside, the malware waits for the Track 2 credit card data and once it has the data, it encrypts and encodes it before sending to the bad guy via a DNS query.

The use of DNS for data exfiltration on PoS devices is not new and shows not only how attackers can adjust to different environments but also, that organizations need to be more aware of their DNS traffic for potential anomalies.

BIG-IP could also help in both instances.

For the redirection issue, BIG-IP or our Silverline Managed Service offers Proxy mode with DNS redirection. With Routed Mode, we offer BGP to Silverline then Generic Routing Encapsulation (GRE) tunnels or L2VPN back to the customer to mask the original IP address.

For the PoS malware, BIG-IP can utilize a DNS response policy zone (RPZ) as a firewall or outbound domain filtering mechanism. An RPZ is a zone that contains a list of known malicious Internet domains. The list includes a resource record set (RRset) for each malicious domain and each RRset includes the names of the malicious domain and any subdomains of the domain.


When the BIG-IP system receives a DNS query for a domain that is on the malicious domain list of the RPZ, the system responds in one of two ways based on your configuration. You can configure the system to return an NXDOMAIN record that indicates that the domain does not exist or return a response that directs the user to a walled garden.

BIG-IP returns NXDOMAIN response to DNS query for malicious domain

BIG-IP forwards DNS query for malicious domain to walled garden

DNS is one of those technologies that is so crucial for a functioning internet, especially for human interaction. Yet is often overlooked or seems to only get attention when things are broken. Maybe take a gander today to make sure your DNS infrastructure is secure, scalable and ready to answer each and every query. Ignoring DNS can have grave consequences.

Is Your DNS Vulnerable?

This article originally appeared on F5.com on 7.29.15.

A recent report from The Infoblox DNS Threat Index (in conjunction with Internet Identity) shows that phishing attacks has raised the DNS threat level to a record high of 133 for second quarter of 2015, up 58% from the same time last year. The biggest factor for the jump is the creation of malicious domains for phishing attacks. Malicious domains are all those very believable but fake sites that are used to mimic real sites to get you to enter sensitive details. You get a phishing email, you click the link and get sent to a financial site that looks and operates just like your real bank site. If you're fooled and enter your credentials or other personal information, you could be giving the bad guys direct access to your money. These sites can also pretend to be corporate portals to gather employee credentials for future attacks.

Along with the malicious domains, demand for exploit kits also helped propel the DNS threat. Exploit kits are those wonderful packaged software that can run, hidden, on websites and load nasty controls and sniffers on your computer without you even knowing.

The Infoblox DNS Threat Index has a baseline of 100, which is essentially the quarterly averages over 2013 and 2014. In the first quarter 2015, the threat index jumped to 122 and then another 11 ticks for Q2 2015, hitting the high mark. Phishing was up by 74% in the second quarter and Rod Rasmussen, CTO at IID, noted that they saw a lot of phishing domains put up in the second quarter. You'd think after all these years this old trick would die but it is still very successful for criminals and with domain names costing less than $20 and available in minutes, it is a cheap investment for a potentially that big score.

DNS is what translates the names we type into a browser (or mobile app, etc.) into an IP address so that the resource can be found on the internet. It is one of the most important components to a functioning internet and as I've noted on several occasions, something you really do not think about until it isn't working...or is hacked. Second to http, DNS is one of the most targeted protocols and is often the source of many attacks. This year alone,  the St. Louis Federal Reserve suffered a DNS breach, Malaysia Airlines' DNS was hacked, and Lenovo.com to name a few. In addition, new exploits are surfacing targeting vulnerable home network routers to divert people to fake websites and DNS DDoS is always a favorite for riff-raff. Just yesterday 3 people were sent to prison in the DNS Changer Case.

With more insecure IoT devices coming on line and relying on DNS for resolution, this could be the beginning of a wave of DNS related incidents. But it doesn't have to be. DNS will become even more critical as additional IoT devices are connected and we want to find them by name. F5 DNS Solutions, especially DNSSEC solutions, can help you manage this rapid growth with complete solutions that increase the speed, availability, scalability, overall security and intelligently manages global app traffic. At F5 we are so passionate about DNS hyperscale and security that we are now even more focused with our new BIG-IP DNS (formerly BIG-IP GTM) solution.

Is 2015 Half Empty or Half Full?

With 2015 crossing the half way point, let's take a look at some technology trends thus far.

Breaches: Well, many databases are half empty due to the continued rash of intrusions while the crooks are half full with our personal information. Data breaches are on a record pace this year and according to the Identity Theft Resource Center (ITRC), there have been 400 data incidents as of June 30, 2015. One more than this time last year. And, 117,576,693 records had been compromised. ITRC also noted a 85% increase in the number of breaches within the banking sector. From health care to government agencies to hotel chains to universities and even Major League Baseball, breaches and attacks are now a daily occurrence.

Cloud: Who would've thought back in 2008 that this cloud thing would now be half full? Over the last couple years, the 'cloud' has become a very viable option for organizations large and small. It is becoming the platform for IoT and many organizations such as Google and GE are now moving critical corporate applications to the cloud. While hybrid is the new normal remember, The Cloud is Still just a Datacenter Somewhere.

DNS: While IPv4 addresses are now completely empty, DNS seems to be half to almost full in 2015. DNS continues to be a target for attackers along with being an enabler for IoT. It is so important that Cisco recently acquired OpenDNS to help fight IoT attacks and the courts got a guilty plea from an Estonian man who altered DNS settings on infected PCs with the DNSChanger malware. I think of DNS as a silent sufferer - you really don't care about it until it doesn't work. Start caring this year.

Internet: Full but still growing. As noted above, IPv4 addresses are gone. Asia, Europe, Latin America and now North America have run out of IPv4 addresses and have exhausted their supplies. If you're wondering how to handle this glass, F5 has some awesome 4to6 and 6to4 solutions.

IoT: Things, sensors and actuators are all the buzz and are certainly half full for 2015. At this time last year, IoT was at the top of the Gartner Hype Cycle and it has certainly not disappointed. Stories abound about Internet of Things Security Risks and Challenges, 10 of the biggest IoT data generators, the Top 10 Worst Wearable Tech Devices So Far, The (Far-Flung) Future Of Wearables, along with the ability to Smell Virtual Environments and if We Need Universal Robot Rights, Ethics And Legislation. RoboEthics, that is.

Mobile: We are mobile, our devices are mobile and the applications we access are now probably mobile also. Mobility, in all it's connotations, is a huge concern for enterprises and it'll only get worse as we start wearing our connected clothing to the office. The Digital Dress Code has emerged. Mobile is certainly half full and there is no empting it now.

Privacy: At this point with all the surveillance, data breaches, gadgets gathering our daily data and our constant need to tell the world what we're doing every second, this is probably bone dry. Pardon, half empty, sticking to the theme.

That's what I got so far and I'm sure 2015's second half will bring more amazement, questions and wonders. We'll do our year in reviews and predictions for 2016 as we all lament, where did 2015 go? There is that old notion that if you see a glass half full, you're an optimist and if you see it half empty you are a pessimist. Actually, you need to understand what the glass itself was before the question. Was it empty and filled half way or was it full and poured out? There's you answer!

IoT Effect on Applications

As more applications are needed to run those Things, traditional infrastructure concerns like scale and reliability will become paramount. Additional challenges with identity and access, improving the user experience, and the need for faster provisioning of services could overwhelm IT departments. A robust, scalable and intelligent infrastructure will be necessary to handle the massive traffic growth.

IT professionals are tasked with designing and building the infrastructure that’s ready for the challenges that lie ahead, including IoT. But many of today’s traditional architectures will buckle under the increasing demand of all the connected devices. According to IDC, the rate at which applications double in the enterprise is every four years. This is likely to be cut in half as more IoT devices need applications supporting them and organizations need to be ready for the deluge.

The Domain Name System (DNS) is the most likely method for connected devices to locate needed services, and it’s potentially the means by which people will locate the devices themselves. There might be other schemas in the planning process, but those would require the adoption of a new technology naming standard, which would be costly, slow and highly unlikely.

Clearly, security must also be present since Iot has the potential to weave vulnerabilities throughout the system. Unless organizations remain proactive, the ubiquity of connected devices presents a gold mine for attackers. Outpacing attackers in our current threat landscape will require more resources in order to minimize risk. Organizations will need to continue to harden our own infrastructures and look to cloud services like DoS mitigation to lessen the effects of attacks.

At the same time, the explosion of embedded devices may well be the event that drives more mainstream IPv6 adoption. There are several advantages to IPv6 such as a large namespace, address self-configuration, and the potential to remove Network Address Translation (NAT) problems. The data center will require some planning to embrace this shift. Components such as routers, firewalls, and application delivery controllers will need to be IPv6-ready, capable of understanding the protocols and data that devices will use to communicate.

To ensure security, intelligent routing, and analytics, networking layers will need to be fluent in the language your devices use. Understanding these protocols within the network will allow traffic to be secured, prioritized, and routed accordingly. Recognizing and prioritizing these messages will enable better scale and manageability of the onslaught of device traffic and data. Intelligence will also be needed to categorize what data needs attention (like a health monitor alert) and what doesn’t (temperature is good).

According to TechTarget, to ensure high availability of IoT services, enterprises must consider boosting traffic management and monitoring. This will both mitigate business continuity risks, and prevent potential losses. From a project planning standpoint, organizations need to do capacity planning and watch the growth rate of the network so that the increased demand for the required bandwidth can be met.
