How to Identify a Security Incident?

It is becoming increasingly rare to see a company that has not experienced an information security incident. This is due to the rise of digitalization, as well as the sophistication of cybercrime.

In this scenario, organizations have a few options:

1. Invest in protective measures to prevent or minimize the damage from security incidents.
2. Wait for the worst to happen before considering what needs to be done, while operations and data integrity are compromised.
3. Not think about information security structurally and leave openings for cybercriminals to exploit.
4. Make information security a part of the organization's culture and prevent security incidents from occurring.

There’s no secret: how you handle data protection affects how your company deals with a security incident—which, as mentioned earlier, are increasingly common.

What is a security incident? A security incident refers to any event that compromises the confidentiality, integrity, or availability of data and information in an information system. These incidents can occur in various ways and have the potential to cause significant harm to organizations, individuals, or systems.

That said, some examples of information security incidents include:

• Data breaches: Unauthorized access to sensitive information or any type of data.
• Malware: Infection by malicious software, such as viruses, trojans, and ransomware.
• Denial of Service (DoS) attacks: Attempts to flood a system, network, or service with excessive traffic, rendering them inaccessible to legitimate users.
• Phishing: Attempts to deceive users into providing confidential information or access.
• Social engineering attacks: Psychological manipulation to obtain confidential information or unauthorized access to systems.
• Exploitation of vulnerabilities: Taking advantage of security flaws in systems or applications.

How to identify a security incident? In addition to having a well-defined response plan, identifying a security incident is crucial for a quick and effective response. Here are some common signs that may indicate the occurrence of an information security incident:

• Abnormal network traffic: Constantly monitoring network traffic is crucial for identifying potential security incidents. Traffic analysis tools, such as IDS (Intrusion Detection Systems), can help identify suspicious patterns. This way, alerts can be generated for unusual traffic that may indicate DoS attacks or exploitation attempts.
• Unauthorized access: Detailed log records are essential for tracking login activities. Monitoring authentication logs can help identify failed login attempts or unauthorized access. To prevent security incidents, implementing multi-factor authentication (MFA) or using passkeys can provide an additional layer of security.
• Unexpected changes in data: Another way to identify security incidents is by using file integrity monitoring tools. These can help detect unauthorized changes to data more quickly and accurately. Additionally, conducting regular audits of data and systems can help ensure their integrity and identify information security incidents.
• Security alerts: Configuring alerts on intrusion detection systems, antivirus software, and other security devices is vital for immediate notification of suspicious activities, as these tools are essential for recognizing emerging threats.
• User reports: Establishing a strong security culture where users are encouraged to report any suspicious activity makes a significant difference in identifying a security incident. This is because vigilance and monitoring the functioning of systems become a natural task across all areas of the company.
• Web server logs: Analyzing web server logs is a good practice for identifying exploitation attempts, unauthorized access, or suspicious activities more accurately and quickly. Therefore, using firewalls to block unwanted traffic is recommended.
• Trend analysis: As technologies evolve, cybercrime becomes more sophisticated, and staying updated on trends in new cyber threats can help facilitate the identification of unusual activities that may indicate a potential security incident.

How does Bug Bounty help prevent security incidents? Bug Bounty is an effective way to identify vulnerabilities in online assets. This allows for the correction of potential flaws before a security incident occurs.

One of the main ways security incidents occur is related to the exploitation of vulnerabilities. By making systems more secure and closing entry points, it is possible to prevent such invasions.
