Your guide to Security Incidents.

Updated: May 9, 2023

In our latest blog post, VISO's Information Security Analyst; Erica Manning explores security incidents; why they occur and how they can be prevented.

In today's world, security incidents are becoming increasingly common, and they pose a serious threat to individuals, organizations, and even entire nations. They come in many forms, including cyber-attacks, physical attacks, and theft, and can result in significant financial losses, reputational damage, and even physical harm.

What are Security Incidents?

A security incident is an event that compromises the confidentiality, integrity, or availability of an organization's information assets. Security incidents come in many forms such as cyber-attacks, physical attacks, theft, and fraud and can involve unauthorized access to sensitive data, theft or loss of data, denial of service attacks, malware infections, or any other activity that could harm an organization's information technology systems or data.

The severity of a security incident can vary depending on the impact it has and the result whether it is financial loss, damage to an organization's reputation, legal and regulatory penalties, and even harm to individuals or communities. Appropriate incident management and response are crucial for minimizing the impact of security incidents and preventing them from recurring in the future.


Why do Security Incidents Occur?

Security incidents can happen for a variety of reasons. Below are some common examples:

  1. Human error: Employees can unintentionally cause security incidents by falling victim to a phishing scams, if they are using weak passwords or using the one password for multiple logins, or mishandling sensitive data.

  2. Malicious activity: Hackers or insiders with malicious intent can exploit vulnerabilities in an organization's systems to steal data, install malware, or hold sensitive data for ransomware.

  3. Technical malfunctions: Technical failures, such as bugs in software or hardware malfunctions can cause a security incident that compromise the confidentiality, integrity, or availability of data.

  4. Physical security breaches: Unauthorized access to facilities, a device holding sensitive data is stolen, or other physical security breaches can lead to security incidents.

  5. Environmental factors: Natural disasters, power outages, and other environmental factors can disrupt an organization's systems and cause security incidents.

By identifying the root cause of a security incident will help organizations understand how the incident occurred and what steps are necessary to prevent them from occurring again in the future. This may involve training employees on security attacks, implementing software patches, introducing password expiry date, or performing regular vulnerability assessments and risk assessments.


How can Security Incidents be Prevented?

Preventing security incidents requires a holistic approach that involves people, processes, and technology. Here are some best practices for preventing security incidents:

  1. Employee education and awareness: Employees can the weakest link in an organization's security posture is they are uneducated on in the area of security. Providing regular training on security best practices and awareness of phishing scams, social engineering, and other threats, it can help your prevent security incidents.

  2. Strong access controls: Implementing strong access controls, such as multi-factor authentication, least privilege access, and password policies, can limit the risk of unauthorized access and data breaches.

  3. Regular vulnerability assessments and risk assessments: performing these assessments are essential for preventing security incidents as they help organizations identify potential weaknesses in their systems, applications, and processes. By identifying vulnerabilities and risks, organizations can take the necessary steps to mitigate them before they are exploited by attackers.

  4. Incident response planning: Having a well-defined incident response plan that outlines roles and responsibilities, procedures, and communication protocols during an active incident can help minimize the impact of security incidents when they occur.

  5. Secure software development: Implementing secure software development practices, such as threat modelling, code reviews, and testing, can reduce the risk of vulnerabilities in software applications.

  6. Patch management: Regularly applying security patches and updates to software and systems can prevent known vulnerabilities from being exploited.

  7. Data backup and recovery: Implementing regular data backup and recovery procedures can ensure that data is protected and can be recovered in the event of a security incident. By adopting a proactive and comprehensive approach to security, organizations can reduce the risk of security incidents and protect their sensitive data and systems.
