Distributed Denial-of-service, or #DDoS, is a persistent threat facing businesses of all types, regardless of geographic location or target market. DDoS tools are becoming easier to use, while the attacks themselves are becoming more complex—frequently combining many different methods in one assault. With attack data from the F5 Silverline Security Operations Center and incidents logged by the F5 Security Incident Response Team (SIRT), I start the clock to check out DDoS Attack Trends for #2020 and read the article.

The Roadblock for Malicious Traffic
In a business environment, security is all about risk: Assessment, analysis, management and mitigation. The many IT security trends like IoT, cloud, device proliferation, disappearing perimeter, and so forth are all potential risks to the business. To reduce their risk, organizations need to ensure they can scale to meet the global workforce’s and customer’s data demand; they need to secure their data from targeted attacks, unauthorized access, inadvertent leakage or to comply with regulatory rules; and they need to keep their operational infrastructure simple and efficient.
The BIG-IP platform offers the scale and capacity to meet the deluge, the full proxy security to protect the applications and infrastructure and the operational efficiency to consolidate functions within an application centric security model. The BIG-IP platform is a full proxy architecture – establishing a TCP connection with the client to the BIG-IP and a separate TCP connection from the BIG-IP to the resources themselves. It is able to apply policies on both ends, anywhere along the stack. This allows organizations to inspect, manipulate or simply drop traffic – on the way in or on the way out - if it does not adhere to the policy. Plus, iRules extensibility gives you the power to do almost anything with the traffic.
BIG-IP Advanced Firewall Manager (AFM) is a stateful, full-proxy, ICSA-certified firewall and brings additional network firewall capabilities at a fine granular level allowing administrators to easily protect their infrastructure and understand what types of attacks are infiltrating the network. Logging and reporting are built-in. BIG-IP AFM can be added to any BIG-IP platform and can help reduce those business risks.
Bringing together security and deep application fluency, BIG-IP AFM delivers the most effective network-level security for enterprises and service providers alike. Whether on-premises or in the cloud, BIG-IP AFM tracks the state of network sessions, maintains application awareness, and mitigates threats based on attack details that most traditional network firewalls simply do not have. It helps you respond to threats quickly and with a full understanding of your security posture. In addition, AFM protects your organization from the most aggressive DDoS attacks before they ever reach your data center.
F5 DevCentral has a whole AFM series coming your way over the next few weeks! The schedule includes:
- March 15th: Foundational / Provisioning – This will kick of the series, taking what John tackled in AFM Provisioning and Policy Building and fleshing out more of the finer details in provisioning and basic policy functionality.

The Malware Mess
A couple weeks ago McAfee Labs released the McAfee Threats Report: Second Quarter 2013, which found that Android-based malware marked a 35% growth rate not seen since early 2012. They also found twice as many new ransomware offerings in Q2 as in Q1, bringing the 2013 ransomware count higher than the total found in all previous periods combined. Everything was in play - SMS stealing bank malware, infected legitimate apps, malicious apps in sheep's clothing, along with fake dating and entertainments apps. A lot of areas that we spend a good portion of our mobile time.
In addition to mobile threats, Q2 also saw a 16% uptick in suspicious URLs and a 50% increase in digitally-signed malware samples. Attackers are showing that they can adapt to the criminal opportunities and continue to infiltrate the ever changing infrastructure. Ransomware, a very popular and profitable scheme, where pop-ups or other messages threaten the user unless they pay a ransom, doubled from Q1 to Q2. Hey, if it works, might as well. Malware signed with legitimate certificates increased 50% to 1.2 million samples. You think you're getting the safe code due to the certificate's authentication but that cozy blanket gets cold quick. Malware also continues to find life with infected URLs according to McAfee. The total number of suspect URLs found reached 74.7 million or a 16% increase over Q1. The Indexed Web is at least 3.82 billion pages so around 2% of the web but still. I might suggest, 'watch what you type, don't click suspicious links, avoid porn sites,' and other rather obvious actions but these days it could be delivered through an ad loading on a popular news site. Almost no one is immune. SPAM continues to hog email servers accounting for almost 70% of all global email volume. That's nuts. Think about it all the legitimate email we send over a month and it only accounts for 30% of all email?!? What a waste of resources. Other highlights included cyber espionage campaigns and attacks on digital currency.
These threats come at a time where there seems to be a disconnect between executives and their technical teams.
The Ponemon Institute's most recent research shows that when it comes to locking down enterprise infrastructure, the application layer is responsible for more than 90% of all security vulnerabilities, yet more than 80% of IT security spending continues to be at the network and endpoint layer. According to Ponemon, 'Most Organizations are Woefully Behind in Application Security.' For it's 'Current State of Application Security Report' , they asked 642 IT professionals (both executive & engineering) 20 questions concerning tools usage, development team knowledge and security best practices to better understand the maturity of an organization’s application security program in comparison to the core competencies of high-performing organizations. They found that a much higher percentage of executive-level respondents believe their organizations are following security procedures through the lifecycle of application development than do the engineers who are closest to executing the security processes. For instance, 71% of executives interviewed believe that application security training is available and up to date but only 20% of technical staff felt the same. Around 67% of execs feel they have a mature application security program, compared to 33% of technical staff and 75% of executives believe that a secure architecture exists in their organization verses 23% of technical staff. Someone is either not communicating or many organizations do not yet consider the need to proactively do something about application security or even attempt to understand application security risks.
What is troublesome is that even with all the media attention and the afore mentioned malware stats, most organizations are not building nor testing their applications for security. According to the Ponemon report, only 43% of respondents say they have a process in place to test for vulnerabilities prior to release, and only 41% are using automated scanning tools to test applications during development. And just to pile on, only 42% push their applications to manual penetration testing by internal teams or from a third party.
So, threats are increasing (I feel like I say this multiple times a year) and it seems that organizations' response to them are decreasing...or at least not taking them seriously enough. In many ways, it is kinda like the real world. We think, feel, believe that we're safe until something happens...then we take all the precautions. Many organizations need to do that yesterday.
Today's technologies are awesome but every once in a while I do miss 4 TV stations (including PBS), typewriters, rotary phones, mimeograph machines, S&H Green Stamps and the hard wires of yesteryear.

Big Data Getting Attention
According to IBM, we generate 2.5 quintillion (2.5 followed by 17 zeros) bytes of data every day. In the last two years, we've created about 90% of the data we have today. Almost everything that's 'connected' generates data. Our mobile devices, social media interactions, online purchases, GPS navigators, digital media, climate sensors and even this blog to name a few, adds to the pile of big data that needs to be processed, analyzed, managed and stored. And you think that saving all your movies, music and games is a challenge.
This data growth conundrum is 3 (or 4 - depending on who you talk to) dimensional with Volume (always increasing amount of data), Velocity (the speed back and forth) and Variety (all the different types - structured & unstructured). Veracity (trust and accuracy) is also included in some circles. With all this data churning, security and privacy only add to the concerns but traditional tactics might not be adequate.
Recently the Cloud Security Alliance (CSA) listed the top 10 security and privacy challenges big data poses to enterprises and what organizations can do about them. After interviewing CSA members and security-practitioners to draft an initial list of high priority security and privacy problems, studying the published solutions and characterizing problems as challenges if the proposed solution(s) did not cover the problem scenarios, they arrived at the Top 10 Security & Privacy Challenges for Big Data.
They are:
- Secure computations in distributed programming frameworks
- Security best practices for non-relational data stores
- Secure data storage and transactions logs
- End-point input validation/filtering
- Real-Time Security Monitoring
- Scalable and composable privacy-preserving data mining and analytics
- Cryptographically enforced data centric security
- Granular access control
- Granular audits
- Data Provenance
The Expanded Top 10 Big Data challenges has evolved from the initial list of challenges to an expanded version that addresses new distinct issues.
- Modeling: formalizing a threat model that covers most of the cyber-attack or data-leakage scenarios
- Analysis: finding tractable solutions based on the threat model
- Implementation: implanting the solution in existing infrastructures
The idea of highlighting these challenges is to bring renewed focus on fortifying big data infrastructures. The entire CSA Top 10 Big Data Security Challenges report can be downloaded here.

Is 2013 Half Empty or Half Full?
It certainly has been a wild ride thus far for 2013 as we head into the second half. Breaches, hacks, exposures, leaks, along with things like BYOD and SDN should make the next 6 months interesting. From the many headlines in 2012, you'd think organizations would be locked down tight but alas, intruders are still kicking a$$ and taking names...literally.
Media and news organizations, like the New York Times and Wall Street Journal, experienced data breaches due to spear fishing and malware. According to various news articles, certain journalists were targeted based on their story coverage but more interesting to me is the fact that the anti-virus along with the IPS/IDS in place failed to catch the malware. Unless there is a signature in place for a known piece of evil code, that demon will make it's way through.
Financial institutions up to and including the Federal Reserve were breached. While many bank hacks are driven by monetary gain, sometimes they are the targets of political activists. Humans are very passionate about their beliefs and like to express those feelings. There have always been protesters and activists - some write letters, some picket on the sidewalk, some throw rocks and with the advent of the internet, now you can protest by creating digital havoc. Instead of hoping that people boycott a particular entity, you can simply take it out yourself so no one can get to the site.
Social media networks continue to feel the heat from breaches. Many social media sites are now deploying two-factor authentication to help reduce password exposures and increase verification checks. Many news stories have talked about password usage and it's good that two factor is being deployed...but,in many cases, it is only after the bad news hits the media. Why wait?
To help organizations understand the various web threats, OWASP has released their Top 10 for 2013 (with changes from 2010 Edition):
- A1 Injection
- A2 Broken Authentication and Session Management (was formerly 2010-A3)
- A3 Cross-Site Scripting (XSS) (was formerly 2010-A2)
- A4 Insecure Direct Object References
- A5 Security Misconfiguration (was formerly 2010-A6)
- A6 Sensitive Data Exposure (2010-A7 Insecure Cryptographic Storage and 2010-A9 Insufficient Transport Layer Protection were merged to form 2013-A6)
- A7 Missing Function Level Access Control (renamed/broadened from 2010-A8 Failure to Restrict URL Access)
- A8 Cross-Site Request Forgery (CSRF) (was formerly 2010-A5)
- A9 Using Components with Known Vulnerabilities (new but was part of 2010-A6 – Security Misconfiguration)
- A10 Unvalidated Redirects and Forwards
Along with their Top 10 Mobile Risks:
- M1: Insecure Data Storage
- M2: Weak Server Side Controls
- M3: Insufficient Transport Layer Protection
- M4: Client Side Injection
- M5: Poor Authorization and Authentication
- M6: Improper Session Handling
- M7: Security Decisions Via Untrusted Inputs
- M8: Side Channel Data Leakage
- M9: Broken Cryptography
- M10: Sensitive Information Disclosure
These are guides to help organizations understand the threats but always make sure you understand you own risks and focus on mitigating those first whether they are on the OWASP Top 10 or not. Then make sure you're covered on the rest.
So far, 2013 has been full of breaches that empties an organization's information.

Small Business is a Big Target
If you think that small businesses are not an enticing enough target to breach, think again. While the media has certainly upped it's coverage over the last couple years pertaining to data loss, many of the headlines involved global brands and tens of thousands records...not the corner deli, the mom/pop shop or the new start up. Yet a couple of recent reports show that small businesses and start-ups are prime targets for data loss.
The annual, chuck full of stats, Verizon Data Breach Report noted that of the 621 confirmed data breaches, almost half happened at companies with less than 1000 employees and almost 200 at companies with less than 100 employees. A Symantec report echoed the finding. In theirs, small businesses with less than 250 employees accounted for 31% of the attacks in 2012, up 18% from 2011. Symantec also notes that start-ups are especially vulnerable in the early going.
Why are these groups targets?
They have valuable data - intellectual property, financial information, digital identities - but may not have the resources to properly protect that data. Many large, global companies have beefed up their security in fear of becoming the next headline in a major newspaper. Thieves usually go after the easiest target - those with limited resources to protect against such an attack. Thieves may also infiltrate a smaller organization to jump on a global network if a partnership is in place. Take out the villages before entering the capital. In a start-up's situation, as they quickly launch, employees may be enticed to click a malicious link in an email...which then spreads. Most startups get infected with malware within the first year.
From marketing organizations to cleaning products to credit repair services, here are some stories of how cyber attacks almost destroyed 5 small businesses.

iRules - Is There Anything You Can't Do?
Ex·ten·si·ble (in programming): Said of a system (e.g., program, file format, programming language, protocol, etc.) designed to easily allow the addition of new features at a later date. (from Dictionary.com)
Whenever I attend a F5 customer or partner gathering, I always ask of those who use iRules, 'Do you deploy iRules due to BIG-IP not having a particular feature or because you need to solve a specific issue within your unique architecture?' Overwhelmingly, the answer is to address something exclusive to the environment.
An iRule is a powerful and flexible feature of BIG-IP devices based on F5's exclusive TMOS architecture. iRules provide customers with unprecedented control to directly manipulate and manage any IP application traffic and enables administrators to customize how you intercept, inspect, transform, and direct inbound or outbound application traffic. iRules is an Event Driven scripting language which means that you'll be writing code based off of specific Events that occur within the context of the connections being passed through the Virtual IP your iRule is applied to.
There are many cool iRule examples on our DevCentral Community site like Routing traffic by URI and even instances where an iRule helped patch an Apache Zero-Day Exploit (Apache Killer) within hours of it being made public and well before the official Apache patch. An iRule was able to mitigate the vulnerability and BIG-IP customers who have Apache web servers were protected. Risk of exploit greatly diminished.
Recently our own Joe Pruitt, Sr. Strategic Architect with the DevCentral team, wrote a cool iRule (and Tech Tip) to Automate Web Analytics. Analysis on the usage patterns of site visitors is critical for many organizations. It helps them determine how their website is being utilized and what adjustments are needed to make the experience as best as possible...among many other things. Joe's article discusses how to use an iRule to inject analytics code into HTML responses to enable the automation of analytics into your website software. Adding a certain piece of JavaScript code into each web page that you would like monitored is one option but what happens if the release criteria for application code requires testing and adding content to pages in production is not allowed or multiple products from multiple application groups reside on a given server or even when 3rd party code is present where you don't have access to all the source that controls page generation.
If you have BIG-IP fronting your web application servers, then you can add Joe's iRule to inject client side JavaScript into the application stream without the application knowing about it. Joe uses Google Analytics as an example, but, according to Joe, it is fairly easy to replace the content of the "analytics" variable with the replacement code for any other service you might be using. Very cool indeed.
So while iRules might not be able to make your coffee in the morning - unless of course it is a slew of IP enabled coffee machines - they can help organizations create extremely agile, flexible and secure environments. Like Oreos and Reese's, there have been a bunch of imitators but nothing is as good as the original.
