Security analytics: The key for breach detection

“Although security spending is at an all-time high, security breaches at major organizations are also at an all-time high, according to Gartner, Inc. The impact of advanced attacks has reached boardroom-level attention, and this heightened attention to security has freed up funds for many organizations to better their odds against such attacks.”
“Breach detection is top of mind for security buyers and the field of security technologies claiming to find breaches or detect advanced attacks is at an all-time noise level,” said Eric Ahlm, research director at Gartner. “Security analytics platforms endeavor to bring situational awareness to security events by gathering and analyzing a broader set of data, such that the events that pose the greatest harm to an organization are found and prioritized with greater accuracy.”
The approach that seems to be in favour at the moment is: security information and event management (SIEM)
“While most SIEM products have the ability to collect, store and analyze security data, the meaning that can be pulled from a data store (such as the security data found in a SIEM) depends on how the data is reviewed. How well a SIEM product can perform automated analytics — compared with user queries and rules — has become an area of differentiation among SIEM providers.”
“User behavior analytics (UBA) is another example of security analytics that is already gaining buyer attention. UBA allows user activity to be analyzed, much in the same way a fraud detection system would monitor a user’s credit cards for theft. UBA systems are effective at detecting meaningful security events, such as a compromised user account and rogue insiders. Although many UBA systems can analyze more data than just user profiles, such as devices and geo-locations, there is still an opportunity to enhance the analytics to include even more data points that can increase the accuracy of detecting a breach.”
“As security analytics platforms grow in maturity and accuracy, a driving factor for their innovation is how much data can be brought into the analysis. Today, information about hosts, networks, users and external actors is the most common data brought into an analysis. However, the amount of context that can be brought into an analysis is truly boundless and presents an opportunity for owners of interesting data and the security providers looking to increase their effectiveness.”
“Analytics systems, on average, tend to do better analyzing lean, or metadata-like, data stores that allow them to quickly, in almost real-time speed, produce interesting findings. The challenge to this approach is that major security events, such as breaches, don’t happen all at once. There may be an early indicator, followed hours later by a minor event, which in turn is followed days or months later by a data leakage event. When these three things are looked at as a single incident that just happens to span, say, three months, the overall priority of this incident made up of lesser events is now much higher, which is why “look backs” are a key concept for analytics systems.”
“Ultimately, how actual human users interface with the outputs of large data analytics will greatly determine if the technology is adopted or deemed to produce useful information in a reasonable amount of time,” said Mr. Ahlm. “Like other disciplines that have leveraged large data analytics to discover new things or produce new outputs, visualization of that data will greatly affect adoption of the technology.”
It will be interesting to see where the industry goes with these new concepts

China’s Great Cannon

“This post describes our analysis of China’s “Great Cannon,” our term for an attack tool that we identify as separate from, but co-located with, the Great Firewall of China. The first known usage of the Great Cannon is in the recent large-scale novel DDoS attack on both GitHub and servers used by GreatFire.org.”
“On March 16, GreatFire.org observed that servers they had rented to make blocked websites accessible in China were being targeted by a Distributed Denial of Service (DDoS) attack. On March 26, two GitHub pages run by GreatFire.org also came under the same type of attack. Both attacks appear targeted at services designed to circumvent Chinese censorship. A report released by GreatFire.org fingered malicious Javascript returned by Baidu servers as the source of the attack. Baidu denied that their servers were compromised.”
“Several previous technical reports have suggested that the Great Firewall of China orchestrated these attacks by injecting malicious Javascript into Baidu connections. This post describes our analysis of the attack, which we were able to observe until April 8, 2015.”
“We show that, while the attack infrastructure is co-located with the Great Firewall, the attack was carried out by a separate offensive system, with different capabilities and design, that we term the “Great Cannon.” The Great Cannon is not simply an extension of the Great Firewall, but a distinct attack tool that hijacks traffic to (or presumably from) individual IP addresses, and can arbitrarily replace unencrypted content as a man-in-the-middle.”
The report is broken down into a number of sections
Section 2 locates and characterizes the Great Cannon as a separate system;
Section 3 analyzes DDoS logs and characterizes the distribution of affected systems;
Section 4 presents our attribution of the Great Cannon to the Government of China;
Section 5 addresses the policy context and implications;
Section 6 addresses the possibility of using the Great Cannon for targeted exploitation of individual users.
I wonder what the next target of the Great Cannon of China will be

New French Surveillance Law

“The new French Intelligence Bill has provoked concern among many of the country’s lawmakers, as well as international NGOs.”
“According to French Human Rights Defender Jacques Toubon, the legislation contravenes the rulings of the European Court of Human Rights”
“Despite boasting the support of France’s two major political parties, the Union for a Popular Movement (UMP) and the Socialist Party (PS), the Intelligence Bill has come in for some strong criticism in France, and it is now also beginning to raise eyebrows abroad.”
“Many international NGOs, have condemned the vague and general nature of the bill. Designed to legalise certain surveillance practices, the bill would also broaden the powers of the security services, giving them the authority to ask private operators to follow and report on the activity of internet users. The debate over using terrorism as an excuse for internet surveillance is already raging in France, since Paris decided to “block” access to certain sites in the wake of the 7 January attacks.”
“But the new bill goes even further. If adopted, it will allow investigators and government agents to intercept private emails and telephone conversations in the name of security, if they are directly linked to an investigation. Agents would be allowed to use new technologies wherever they deem necessary, including microphones, trackers and spy cameras. They would also be able to intercept conversations typed on a keyboard in real time. All these interceptions would be authorised by the Prime Minister, without the prior approval of a judge, and would be authorised after the fact by a new administrative authority, the National Commission for the Control of Intelligence Techniques (CNCTR).”
“Seven companies, including web hosting and technology companies OVH, IDS, and Gandi have said in a letter to the French prime minister Manuel Valls that they will be pushed into de facto “exile” if the French government goes ahead with the “real-time capture of data” by its intelligence agencies.”
Letter to French Prime Minister (in French)
This has caused a very large backlash from the IT community
Especially some of the large Internet and Server providers like Gandi, OVH, IDS, Ikoula and Lomaco who have threatened to leave France if the law passes
OVH and Gandi threaten to move their operations, customers, tax revenue, and most importantly, 1000s of high tech jobs
Hopefully this sends a clear warning to the US and other countries who are considering or proposing similar legislation, or who’s intelligence agencies have run amok
“The companies argued that being required by the law to install “black boxes” on their networks will “destroy a major segment of the economy,” and if passed it will force them to “move our infrastructure, investments, and employees where our customers will want to work with us.” Citing a figure of 30-40 percent of foreign users, the companies say their customers come to them “because there is no Patriot Act in France,” France’s surveillance bill (“projet de loi relatif au renseignement”) allows the government’s law enforcement and intelligence agencies to immediately access live phone and cellular data for anyone suspected of being linked to terrorism. These phone records can be held for five years.”
