The Last Security Tool
THE REAL SECURITY CHALLENGE
There is a new area of challenge to the security teams in the enterprise, government and education sectors – the constant attack by hackers or other adversaries that are sponsored by a government entity or are part of organized crime.
The attackers are finding new and advanced techniques to break the security measures in place, and security staff now have to concede that when the attackers are determined and well-funded, they will ultimately breach the defenses systems of any organization on the Internet.
Growing network speeds, now routinely hitting 100 gigabitsper-second, or roughly 70 million times faster than the typical network connection when firewalls were introduced, pose a number of challenges, particularly in the area of security. Network growth along with the data deluge puts a great amount of pressure on organizations to combat cyber threats and analyze cyber-attacks in real-time so that necessary actions can be taken with minimum delay.
Post analysis of the data, after a threat or security breach, is critical for all organizations. The analysis allows management to make decisions and take actions in response to an attack. More importantly, it is needed to ensure that a cyber event has been truly resolved so that all public disclosure, notification of impacted parties and internal remediation can be completed.
We live in an age where cyber-attacks on high-speed networks are at an all-time high and increasing. However, in most cases the attacks are only discovered weeks later. Network security solutions are facing a two-fold growth challenge. Data traffic is increasing exponentially, so there is more to analyze at faster speeds. At the same time, cyberattacks are also growing in number and complexity.
In the never-ending race to combat security breaches, there is no shortage of security alerts or events in a given firm’s environment, in fact just the opposite. Entire industries have been created to fulfill the need to process the tens of billions of events generated every day in a typical large enterprise. The security team faces the huge task of collecting this data from all the tools and then need to prioritize them by severity.
However even with this enormous number of events reported, organized and prioritized, the tools often give either incomplete or contradictory information about a given event. Add to this that once an attacker is inside, he will often compromise the credentials of a legitimate user and might disguise himself as an employee to do searches and extract sensitive data.
In 2014, average costs for data breaches rose (USD 5.9 million, up from to USD 5.4 million), lost business (USD 3.2 million, up from USD 3.03), and lost or stolen records (USD 246 per). Malicious or criminal attacks are the main cause (44%)1. Worse, these direct expenses often are just the first of many legal, shareholder, employee, regulatory, customer and reputational ripples (See figure 1). While, detection and escalation costs rose to USD 417,700, up from USD 395,262 over the past year.2 Post-data breach response and detection costs rose to USD 1.6 million, up from approximately USD 1.41 million3 (See figure 2).
DEFENSE IN DEPTH
With so much at stake, organizations need to implement a diverse solution that 1) prevents intrusion, 2) alerts on suspicious activity, 3) continuously collects forensics data so that the inevitable breach is fully captured and 4) offers post analysis possibilities “It is no longer possible to rely on one single security solution. Traditional point defenses cannot adequately address the new, faster-moving, multi-layer threats and more sophisticated attackers,” says Daniel Joseph Barry, Vice President of Positioning and Chief Evangelist of Napatech. “What’s required is a layered approach with defense-in-depth, where we not only rely on network security appliances for indications of data breaches, but also network behavior analysis.”
Continuously recorded network data is the “last security tool”. A network forensics solution should continuously capture all data 24×7 regardless of whether anything interesting is happening in a particular moment or not. Then in conjunction with alerts from the other tools, the security team can investigate whether the event was a false alarm or something that needs to be actioned. Moreover, they can see what happened after the breach and achieve the ultimate goal: determining all the assets the attacker may have accessed and whether he has truly been eliminated from their environment.
A PURPOSE BUILT FORENSICS TOOL
Although many tools can provide a partial network recording based on an event, that data is inevitably incomplete if the recording tool did not see anything it considered interesting. For effective network forensics, we need a tool that can record everything continuously at high speed. It must be purpose-built for this since the demands for storage and indexing of this volume of data are much different than the architecture of the other security tools.
Real-time data capture can be taken a step further by introducing the concept of data capture and retrieval on-demand. The network forensics solution must provide an immediate and indexed answer to an investigator pursuing an event. It is crucial that security officers can quickly go to the time and place of the event to start our analysis, and waiting several hours for this initial answer can cause serious delays while our attacker may still be inside. One of the challenges faced by CTOs and IT managers is the exponential growth in the volume of data. Storing and analyzing every single data packet can be a tedious task and often very expensive. Hence the need for retrieving data on-demand with a few simple commands, where users can access the packets from a certain server or time-period, in order to get to the root of the problem. So retrieval speed and the need for data on-demand is just as important as capturing it.
The Napatech Pandion Flex is the latest offering from Napatech and is a cost-effective, highly reliable network recorder that guarantees 100% data capture and retrieval on demand inreal-time.
