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.

BRIDGE MODE AND NAT MODE AP

  BOTH BRIDGE MODE AND NAT MODE ARE WAYS TO CONFIGURE AN ACCESS POINT (AP) TO EXTEND A NETWORK, BUT THEY DIFFER IN HOW THEY HANDLE IP ADDRESSES AND NETWORK TRAFFIC: BRIDGE MODE: CONCEPT: ACTS AS A TRANSPARENT BRIDGE, SIMPLY RELAYING DATA BETWEEN WIRED AND WIRELESS DEVICES. IP ADDRESS: DEVICES OBTAIN THEIR IP ADDRESSES FROM AN UPSTREAM DHCP SERVER, TYPICALLY THE MAIN ROUTER ON THE NETWORK. NETWORK TRAFFIC: ALL DEVICES, BOTH WIRED AND WIRELESS, ARE SEEN AS PART OF THE SAME NETWORK AND CAN DIRECTLY COMMUNICATE WITH EACH OTHER. BENEFITS: SEAMLESS ROAMING: DEVICES CAN EFFORTLESSLY SWITCH BETWEEN APS WITHOUT LOSING THEIR IP ADDRESS OR CONNECTION. SIMPLIFIED NETWORK MANAGEMENT: ALL DEVICES ARE ON THE SAME SUBNET, MAKING CONFIGURATION AND TROUBLESHOOTING EASIER. INCREASED COMPATIBILITY: WORKS WITH DEVICES THAT DON'T SUPPORT NAT TRAVERSAL (E.G., SOME VPN CLIENTS). DRAWBACKS: LESS SECURITY : ALL DEVICES ARE DIRECTLY EXPOSED TO EACH OTHER, POTENTIALLY INCREAS

What Is A Ip Excluded Address

  AN IP EXCLUDED ADDRESS IS AN IP ADDRESS THAT HAS BEEN CONFIGURED ON A DHCP SERVER TO BE EXCLUDED FROM THE POOL OF ADDRESSES THAT CAN BE ASSIGNED TO DHCP CLIENTS.  THIS IS TYPICALLY DONE TO RESERVE IP ADDRESSES FOR SPECIFIC DEVICES, SUCH AS PRINTERS, SERVERS, OR OTHER NETWORK DEVICES THAT NEED TO HAVE A STATIC IP ADDRESS. IP EXCLUDED ADDRESSES CAN ALSO BE USED TO PREVENT DHCP CLIENTS FROM RECEIVING IP ADDRESSES THAT ARE ALREADY IN USE BY OTHER DEVICES ON THE NETWORK.  THIS CAN HELP TO AVOID IP ADDRESS CONFLICTS AND IMPROVE NETWORK PERFORMANCE. TO CONFIGURE AN IP EXCLUDED ADDRESS ON A DHCP SERVER, YOU WILL NEED TO KNOW THE IP ADDRESS THAT YOU WANT TO EXCLUDE. ONCE YOU HAVE THE IP ADDRESS, YOU CAN USE THE APPROPRIATE DHCP SERVER CONFIGURATION COMMANDS TO ADD THE IP ADDRESS TO THE EXCLUSION LIST. SOME EXAMPLES OF WHEN YOU MIGHT WANT TO USE IP EXCLUDED ADDRESSES: TO RESERVE AN IP ADDRESS FOR A SPECIFIC DEVICE, SUCH AS A PRINTER OR SERVER. TO PREVENT DHCP CLIENTS FROM RECEIVING I

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.
