The delay in a cyberattack detection can result into serious negative outcomes. The main risk is related to critical data compromise. When an attack happens, an organization faces the risk of data and financial loss; if the attack is detected lately, the list of risks is extended with reputational ones, especially if the compromised data is exposed on third-party resources. What’s more, if a cyberattack is detected lately, there is high probability that intruders will manage to take large part of the organizations’ infrastructure under control, what significantly hinders chances for successful countering attack. Basically, there is relatively high chance that the only solution will be a total blackout and isolation of the network from external resources. Only after, IS officers will be able to proceed to dealing with the existing problems. Delay in a cyberattack detection can lead to the extension of the attack landscape, what hinders tackling attack, reduces chances for successful mitigation of attack’s consequences etc.
So, the question arises, how to detect a cyberattack just in time and what are the best practices for cyber attack detection?
Cyberattacks may be initiated both from the outside and from inside; they may be performed with the help of social engineering techniques or with the help of some technical methods solely. Basically, any IT infrastructure is a set of nodes, and each node may be attacked. So, it’s required to choose and implement some specific tool for protection of each infrastructure’s node. The choice of the best protective tools also depends on what exactly has to be protected. I mean, that in some specific case the best protective tool is anti-virus; in another situation the best protective solution is firewall; in third case DLP system is required.
Most often cyber attacks are complex, thus it’s impossible to detect attacks basing on data, gathered on some single endpoint, thus, it’s required to collect data from different nodes and analyze it. In other words, it’s required to implement the complex approach to ensuring information security. The complex approach requires:
Combination of these techniques, or, in other words, implementation of the complex approach is one of the most crucial issues for detection of a cyberattack just in time.
There is one more issue, crucial to speed up the response to a cyberattack. It is essential that every user understands that a cyberattack sooner or later will affect any organization, and that the volume of its destructivity depends directly on the level of organization’s preparedness to counter a cyberattack. Thus, it’s of crucial importance that:
Besides, in the current circumstances, when cyber threat landscape is permanently and rapidly changing, more and more threats occur and intruders’ techniques become more and more sophisticated, it’s of crucial importance to permanently increase users’ awareness in InfoSec related issues. First of all, IS and IT department employees must stay up to date, however, it’s also very important that they should also permanently help other employees and executives to enhance there is related competencies.
