Intrusion Detection System, Access Control and Auditing

 

Intrusion Detection Systems 

Intrusion Detection Systems (IDS) are critical tools used to safeguard a network by continuously monitoring for suspicious activities or security policy violations. They can analyse network traffic, user activities, and system behaviours to detect potential threats in real-time, alerting administrators to take action.

There are two main types of IDS:

·       Host-Based IDS (HIDS): Operates on individual hosts or devices, monitoring system logs, file integrity, and application activities to detect anomalies or unauthorized actions on that specific device.

·       Network-Based IDS (NIDS): Monitors the entire network by examining packets of data transmitted over the network to identify unusual patterns or signs of attack. It provides a broader view, ensuring the security of the entire network infrastructure.

 

Access Control and Auditing

Access control involves setting permissions and policies to ensure that only authorized users can access certain data or perform specific actions, minimizing the risk of unauthorized access and potential breaches.

Auditing systematically reviews and analyses logs and records of system activities to detect any irregularities or security incidents.

By employing access control measures to limit access and implementing regular auditing to monitor and review system activities a robust security framework is create to protect the systems from threats and ensures compliance with security policies.

Robust password and encrypted data

  Password Policy and Strong Password Create a robust password policy is essential for ensuring and safeguarding the security of user accounts and protecting sensitive information from unauthorized access. A strong password should mandate: ·        At least 16 characters long. ·        A mix of uppercase and lowercase letters. ·        Numbers, and special characters. ·        It should avoid common words. ·        Avoid predictable patterns and personal information that could be easily guessed. To further enhance security, the policy should include timeouts on false attempts and locking accounts after a set number of failed login attempt and password expiration policies should be enforced to require users to change periodically ideally every 90 days. Example of strong password P@m1y2Ds$hz!ne%c Why This Password is...

  Data Controller Notification Requirements (UK vs US): In the UK, data controllers must notify their data subjects of data security breaches that pose a high risk to individuals' rights and freedoms, according to the General Data Protection Regulation (GDPR). Notification should occur "without undue delay" and, where feasible, within 72 hours of the breach being discovered. In the US, there is no single federal law mandating data breach notification. Instead, notification requirements vary by state, with different laws governing when and how individuals must be notified of breaches.   The Largest Data Breach of the 21st Century: The largest data breach occurred with Yahoo in August 2013, which was discovered and publicly disclosed in December 2016. Data breach details include: Number of Records Stolen : 3 billion user accounts Type of Data Exposed : Usernames, email addresses, hashed passwords, and security questions and answers Method of Atta...
