Recognising cyberattack in YOUR companY
Companies can recognize that they are under a cyberattack by being vigilant and implementing robust security measures. Here are 10 signs and methods that can help identify a cyberattack:
- Network Traffic Analysis:
Companies should monitor their network traffic for any unusual or suspicious activities. A sudden increase in data transfers, unexpected connections to unfamiliar IP addresses, or large amounts of outgoing data can indicate a potential cyber attack.
- Intrusion Detection Systems (IDS):
IDS tools can detect and alert organizations to potential security breaches or unauthorized access attempts. These systems analyze network traffic patterns and compare them against known attack signatures or abnormal behavior.
- Anomaly Detection:
Implementing anomaly detection systems can help identify unusual or abnormal behavior in the network or system. This involves establishing baseline behavior patterns and then flagging any deviations from the norm, which may indicate a cyber attack.
- Endpoint Protection:
Endpoint Protection solutions, such as antivirus software and host intrusion detection systems, can detect and block malicious software or unauthorized activities on individual devices. Unusual behavior or the detection of malware on endpoints can be a sign of a cyber attack. Lesen Sie mehr über unsere Zero Trust Platform mit Lösungen für Endpoint Security und Endpoint Protection.
- Security Information and Event Management (SIEM):
SIEM systems collect and analyze security-related logs from various sources, including network devices, servers, and applications. By correlating events and identifying patterns, SIEM can help organizations detect cyber attacks and respond promptly.
- Phishing Awareness:
Educating employees about phishing techniques and encouraging them to report suspicious emails or messages can help identify targeted attacks. Monitoring and analyzing email traffic for phishing attempts can also aid in detecting cyber threats.
- System Performance Issues:
Unexpected slowdowns, crashes, or unavailability of critical systems may indicate a cyber attack. Attackers often exploit vulnerabilities, causing disruptions in system performance or denial of service.
- Unusual Account Activities:
Monitoring user accounts for unusual activities, such as failed login attempts, unauthorized access, or privilege escalation, can help identify potential cyber attacks. Implementing multi-factor authentication and access controls can enhance security in this regard.
- Security Incident Response Planning:
Having a well-defined incident response plan in place can ensure a swift and effective response when a cyber attack occurs. This plan should include steps to isolate affected systems, analyze the attack, mitigate the damage, and restore normal operations.
- Threat Intelligence:
Staying updated on the latest cyber threats, vulnerabilities, and attack techniques through threat intelligence sources can help companies proactively recognize signs of an ongoing or imminent cyber attack.
10 steps to take when your company is a Cyber Attack
If you discover that your business has been the victim of a cyberattack, it is important to act quickly to limit the damage and minimise the impact on your business. Here are the essential steps you should take:
- Activate Incident Response Plan: If your company has an incident response plan in place, follow it immediately. The plan should outline the necessary steps and responsibilities for addressing cyber attacks. Notify the relevant stakeholders, such as IT staff, management, and legal personnel, about the incident.
- Isolate Affected Systems: Quickly isolate the affected systems from the network to prevent further spread of the attack. Disconnect compromised devices or affected servers from the network to limit the attacker's access and protect other systems.
- Preserve Evidence: Preserve any evidence related to the cyber attack. Document any unusual activities, take screenshots, and collect logs and other relevant information. This evidence can be valuable in investigating the incident, identifying the attacker, and pursuing legal action if necessary.
