As the world transforms into a more and more technology dependant place, cybersecurity becomes a concerning issue. Various cyber threats may cause trouble to average users as their compromised data can be used as blackmail or result in significant financial damage to businesses or organizations. Therefore, it is crucial to be able to prevent occurrence of such threats or at least pursue a specific strategy to minimize the damage.
An incident response plan or strategy should be developed against possible cybersecurity flaw. Such plan or strategy represents a list of steps, which should be immediately taken in case of a cyber-attack to limit the potential damage and reduce expenses (Voigt, 2018). According to most sources there are generally six or seven steps that may be the solution to the emerged cyber problem.
First of all, to minimize the risks and consequences of cybersecurity flaw, preparation phase should be established. During the above-mentioned phase cybersecurity team, its instruments, course of action, documentation norms and response strategies should be established (Voigt, 2018). The second step requires the cybersecurity team to detect the threat and collect as much information as possible. Using the accumulated data a detailed analysis of the incident needs to be conducted. Discernment of attack angle is an important part of that stage as it may bring the understanding of the nature of the cyber threat, which accelerates the next steps. Deterrence of the discovered threat is supposed to not let it spread to the whole system by isolating the damaged component. The fifth step is the elimination of the problem, which should result in confirmation of malicious software removal. The last stage includes recovery and post-incident analysis, which should help to prevent similar cyber-attacks in the future.
