Cyber Attack? Here Are 3 Smart Steps to Regain Control Fast

Publish Date: May 15

Cyber attacks are now a common thing in the modern world and are responsible for causing extensive harm to the various parties involved. Considering cyber threats, such as cyber attacks, data leaks, ransomware, and others, including Distributed Denial of Service (DDoS) attacks, the outcome is quite severe, resulting in financial losses, loss of reputation, and violations of business operations.

Prevention only goes a long way, but it is equally important to draw a likely strategy for quick recovery when cybercriminals have succeeded in penetrating the system.

If this is not done soon and in a proper way, then the impact of such intrusion increases, which further puts systems and the data at a higher risk of being exploited.

This is why the existence of a viable and all-encompassing response plan to recuperative cyber attacks is of utmost importance to assess the kind of, and the extent to which, the organization's operation may be compromised, and to be able to get back on its feet as soon as possible.

Recovery Steps & Strategies

Investigate and Analyze the Attack

First, it is necessary to stop the attack and proceed to a detailed investigation to identify the main cause, the methods used, and the possible consequences of the cyber attack.

This may entail scanning the affected systems and logs for evidence, consultations with cybersecurity experts or law enforcement personnel, and reviewing the pen test to determine any weaknesses that the attackers might have capitalized on.

It is for this reason that the attack characteristics, particularly its vector and procedure, must be identified to make a recovery plan that can be followed so that measures against future threats can be put in place.

For effective attack analysis, the investigation should provide answers to preanalytical questions, including how the attack started, which systems were targeted as well, and the various techniques used by the attackers.

Identify and Contain the Breach

The investigation and understanding of the extent of the data breach is the first and most crucial process that needs to be undertaken when responding to a cyber attack.

This involves the identification of the first sign of the compromise and how the attacker got in, the identification of the systems, network, or data that has been affected, determination of the type of attack it may be malware, phishing, or unauthorized access among others, and determination of the potential extent of the compromise and damages.

After the breach is confirmed, it is important to prevent the spread of the contamination to other systems and networks of the organization. It can also assist in not letting the attack escalate further, thereby reducing impacts.

Mitigation steps can be as simple as physically isolating infected computers and networks, preventing important data transfer, or temporarily limiting the network permissions.

Activate Your Incident Response Plan

Any organization needs to have a road map, so to speak, of how it should act when it is under attack from cybercriminals. This should indicate which staff members will do what at what time, how staff will communicate with other relevant parties internally and externally, specific details of containment, investigation, and restoration, as well as emergency contacts for law enforcement, technical personnel, or lawyers.

When you 'activate' your incident response plan, you prepare all those who are involved and need to be involved in handling the incident, avoiding confusion and adding more value to the cause of handling the incident effectively.

Specific, measurable tasks should be conveyed, and role responsibilities have to be clearly defined to ensure all relevant stakeholders are aware and in synch with the occurrence and development of the recovery plan.
