Key Aspects of Information Security

Information security ensures the confidentiality, integrity, and availability (CIA) of data across physical, digital, and human components. Core aspects include:

1. Encryption

Encryption is the process of converting data into unreadable code that can only be accessed by authorised users with the correct decryption key. This protects sensitive information such as personal details, financial records, or medical data from unauthorised access.

2. Endpoint Security

Endpoint security protects devices like computers, laptops, mobile phones, and servers from threats. It includes antivirus software, firewalls, device management tools, and monitoring systems to prevent malware, ransomware, and unauthorised access.

3. Physical Security

Information security also considers physical measures to protect data, such as:

• Locked server rooms and restricted access to IT infrastructure
• Security cameras and surveillance systems
• Secure storage of sensitive documents and backups

4. Policies and Procedures

Information security involves establishing rules and processes for handling data securely. Examples include:

• Access control policies specifying who can view or edit information
• Data retention and disposal protocols
• Incident response plans for handling breaches

Why Information Security is Important

In today’s digital age, almost every aspect of life—communication, shopping, banking, healthcare, transportation, and entertainment—is connected to the internet. As a result, vast amounts of personal and organisational data are stored online. Without proper information security measures:

• Sensitive personal data can be stolen or misused
• Business and government data can be compromised, causing financial or reputational damage
• Systems and operations can be disrupted

Both cybersecurity and information security are critical for safeguarding this data. While cybersecurity focuses on protecting systems from external attacks, information security ensures that all forms of data—digital, physical, or human—remain safe, accurate, and accessible to authorised users.

Common Cyberattacks and Threats

Cyberattacks come in many forms, but three of the most common are phishing, ransomware, and social engineering.

1. Phishing: Trick users into clicking malicious links or downloading malware via emails, texts, or social media. Often used to steal passwords, banking info, or personal data.

2. Ransomware: Malware that encrypts files or systems, demanding a ransom for access. Paying doesn’t guarantee data recovery. Attacks have increased 13% in the past five years, costing millions per incident.

3. Social Engineering: Manipulates individuals to reveal sensitive information through impersonation, pretexting, or baiting. Attackers often pose as IT staff or trusted contacts.

Protection Tips:

• Keep software and systems updated
• Use antivirus and endpoint security
• Train users to recognise phishing and suspicious requests
• Maintain secure backups
