Cyber security refers to the practice of protecting systems, networks, and programs from digital attacks. These cyberattacks are usually aimed at accessing, changing, or destroying sensitive information, extorting money from users, or interrupting normal business processes. Implementing effective cybersecurity measures is particularly challenging today because there are more devices than people, and attackers are becoming more innovative.
Functions of Cyber Security
- 1. Protecting Data: Cyber security ensures the protection of sensitive data such as personal information, financial data, and intellectual property.
- 2. Securing Networks: It involves securing networks from unauthorized access and ensuring the integrity of network data.
- 3. Preventing Unauthorized Access: Measures are put in place to prevent unauthorized access to computer systems.
- 4. Mitigating Risks: Cyber security practices help to identify and mitigate potential security risks before they can be exploited by attackers.
- 5. Ensuring Business Continuity: By protecting against attacks, cyber security ensures that business operations continue smoothly without disruption.
- 6. Compliance with Regulations: Helps organizations comply with various regulations that mandate the protection of data.
How Cyber Security Helps Normal People
- 1. Protecting Personal Information: Cyber security helps individuals protect their personal information such as social security numbers, credit card information, and personal emails from being stolen or misused.
- 2. Preventing Identity Theft: By securing personal data, it prevents identity theft which can have severe financial and legal consequences.
- 3. Securing Online Transactions: Ensures that online transactions are safe and secure, protecting individuals from fraud.
- 4. Safe Online Experience: Provides a safe online experience by protecting devices from malware and other cyber threats.
- 5. Peace of Mind: Knowing that their data and devices are secure gives individuals peace of mind.
Features of Cyber Security
- Firewalls: Act as a barrier between trusted and untrusted networks, monitoring and controlling incoming and outgoing network traffic.
- Antivirus and Anti-malware Software: Detect and remove malicious software to prevent infection.
- Intrusion Detection Systems (IDS): Monitor networks for suspicious activities and potential threats.
- Encryption: Protects data by converting it into a coded format that is unreadable without a decryption key.
- Access Control: Ensures that only authorized users have access to certain data or systems.
- Multi-Factor Authentication (MFA): Adds an additional layer of security by requiring multiple forms of verification.
- Regular Updates and Patching: Keeping software and systems up to date to protect against known vulnerabilities.
