When threats are detected, the entire security ecosystem is scanned to identify malicious activities that could compromise the network. If a threat is detected, mitigation measures must be taken to properly neutralize the threat before existing vulnerabilities can be exploited.
A breach is a nightmare scenario, and most companies that prioritize their information use smart people and technology as a barrier to anyone trying to cause trouble. However, security is an ongoing process, not a guarantee.
As part of a company’s security program, the concept of “threat detection” is diverse. Even the best security programs must plan for the worst case scenario when someone or something overcomes their defensive and preventive technologies and becomes a threat.
Speed is critical when it comes to identifying and mitigating threats. Security programs must be able to identify threats quickly and efficiently so that attackers do not have enough time to search for sensitive data. Ideally, a company’s defense programs can stop most threats because they have been seen many times, which means they should know how to combat them. These threats are considered “known” threats. However, there are additional “unknown” threats that a company wants to identify. This means that the organization never knew about them, possibly because the attacker was using entirely new methods or technologies.
Known threats can sometimes overlook the best countermeasures, which is why most security organizations actively search for known and unknown threats in their area. How can an organization try to identify known and unknown threats?
There are several methods available in the defender’s arsenal that can help. With cyber detection services / Threat Intelligence, previously viewed attack signature data can be viewed and compared to company data to identify threats. This makes it particularly effective in detecting known but not unknown threats. Threat Intelligence is often used with great impact in the areas of Security Information and Event Management (SIEM), Antivirus, Intrusion Detection System (IDS), and Web Proxy Technologies.
Analysis of the behavior of users and attackers.
By analyzing user behavior, a company can gain a basic understanding of how an employee typically behaves: what kind of data they access, when they log in, and where they are physically, for example. In this way, sudden atypical behavior, such as 2:00 p.m. Check-in in Shanghai by someone who normally works in New York City from 9:00 a.m. At 5:00 am. and does not do business, it stands out as unusual behavior as something a security analyst may need to investigate.
When analyzing the behavior of attackers, there is no “basis” for the activities against which the information can be compared. Instead, small, seemingly unrelated activities that are recognized over the network over time can actually be crumbs of activities an attacker leaves behind. It takes both technology and the human mind to put these pieces together. However, it can help create a picture of what an attacker is doing on a company’s network.
