Types of Security in Network

 

There are several types of security in a network, covering both physical and digital aspects. Here’s an overview of some key types:

1. Physical Security

  • Surveillance Systems: Includes CCTV cameras, motion detectors, and access control systems to monitor and secure the physical premises where network hardware is located.
  • Access Control: Securing access to data centers, server rooms, and network cabinets through locks, biometric systems, key cards, etc.

2. Network Security

  • Firewalls: Devices or software that monitor and control incoming and outgoing network traffic based on security rules.
  • Intrusion Detection and Prevention Systems (IDPS): Tools that detect and possibly prevent unauthorized access or attacks.
  • Virtual Private Network (VPN): Secure connections over public networks, ensuring data privacy and encryption.
  • Network Access Control (NAC): Policies and protocols that restrict unauthorized devices from accessing the network.
  • Antivirus and Anti-malware: Protects network devices from malicious software.
  • Data Loss Prevention (DLP): Prevents sensitive data from being shared, lost, or stolen.
  • Zero Trust Architecture: A security model where no user or device is trusted by default, even if they are within the network perimeter.

3. Wireless Security

  • Wi-Fi Security Protocols: Such as WPA3, WPA2, or WEP, which protect wireless communications.
  • Rogue Access Point Detection: Identifying unauthorized access points that may compromise the network.

4. Endpoint Security

  • Device Management: Tools like Mobile Device Management (MDM) and Endpoint Detection and Response (EDR) ensure that all devices accessing the network comply with security policies.
  • Patching and Updates: Regular updates to close security vulnerabilities on connected devices.

5. Application Security

  • Web Application Firewalls (WAF): Protects web applications from common attacks like SQL injection, cross-site scripting (XSS), etc.
  • Secure Coding Practices: Implementing code that is resistant to attacks and vulnerabilities.

6. Cloud Security

  • Identity and Access Management (IAM): Manages user access and privileges in cloud environments.
  • Data Encryption: Encrypting data both at rest and in transit within cloud services.
  • Security Posture Management: Tools that continuously assess and manage cloud security configurations.

7. Operational Security (OPSEC)

  • Incident Response Plans: Procedures to follow in the event of a security breach.
  • Regular Audits and Penetration Testing: Testing the network to identify vulnerabilities and improve defenses.

8. Surveillance Security

  • Network Video Recorders (NVR): Used for managing and storing video surveillance feeds.
  • Camera Systems: Includes IP cameras that are connected over the network to monitor areas.
  • Security Information and Event Management (SIEM): Integrates surveillance data with other security information for a comprehensive security view.

9. Human Security

  • Security Awareness Training: Educating employees about threats like phishing, social engineering, and best practices for security.
  • Access Management: Controlling who has access to what information based on their role and need.

DOS AND DDOS ATTACK

A Dos (Denial-Of-Service) Attack and A DDOS (Distributed Denial-Of-Service) Attack Are Both Attempts to Make a Computer System or Network Resource Unavailable to Legitimate Users. However, They Differ in How They Achieve This: Dos Attack: Imagine A Single Person Throwing Rocks at A Castle Gate. A This Person Represents the Attacker, And the Rocks Represent the Malicious Traffic. The Castle Gate Represents the Target System or Network Resource. The Attacker Keeps Throwing Rocks, Trying to Overwhelm the Gate's Defenses and Gain Entry. Dos Attacks Are Typically Launched from A Single System. They Can Be Effective Against Small Systems or Networks, But Larger Systems Can Often Withstand Them. DDos Attack: Imagine An Army Throwing Rocks at A Castle Gate. This Army Represents the Attacker, And the Rocks Represent the Malicious Traffic. The Castle Gate Represents the Target System or Network Resource. The Attackers Coordinate Their Attack, Throwing Rocks from Multiple Directions at Once. ...

Types Of Attack in Network

Common Network Attacks Explained. 1. Overwhelming a Network (DoS/DDoS): Imagine a restaurant that's flooded with too many customers. In a DoS/DDoS attack: A website is overwhelmed with too much traffic. 2. Eavesdropping on Conversations (MitM): Imagine someone listening in on your phone call. In a MitM attack: An attacker listens to your online conversations. 3. Tricking You (Phishing): Imagine receiving a fake email from your bank. In phishing: Attackers try to trick you into giving them your personal information. 4. Finding a Weakness in a Website (SQL Injection): Imagine finding a hole in a fence. In an SQL injection attack: An attacker finds a weakness in a website to steal or change data. 5. Planting a Hidden Camera (XSS): Imagine someone hiding a camera in a party. In an XSS attack: An attacker hides harmful code on a website to spy on you. 6. Guessing Your Password (Password Attck): Imagine trying to guess a friend's password. In a pas...
