How does the SSL protocol guarantee network security?
The SSL (Secure Sockets Layer) authenticates the sender and establishes secure connections between the browser and web server. Still, it does not offer security once the data has been sent to the server. That’s why server-side encryption and hashing are necessary to guard against data breaches. HereRead more
The SSL (Secure Sockets Layer) authenticates the sender and establishes secure connections between the browser and web server. Still, it does not offer security once the data has been sent to the server. That’s why server-side encryption and hashing are necessary to guard against data breaches.
Here’s the general procedure for establishing an SSL connection:
- A browser tries to establish a connection with an SSL-secured web server.
- A copy of the browser’s SSL certificate is sent to the browser.
- The browser verifies the SSL certificate’s trustworthiness. If it is reliable, the browser notifies the web server that it wants to create an encrypted connection.
- The web server transmits an acknowledgment to create an SSL-encrypted connection.
- The web server and browser communicate using SSL encryption.

Here are the steps to install a firewall:
- Username/password: Change a firewall device’s default password
- Remote administration: Turn off the remote administration feature.
- Port forwarding: Set up the proper port forwarding to ensure applications like a web or FTP server function properly.
- DHCP server: Disable the firewall’s DHCP server to ensure no conflict.
- Logging: Enable logging and learn how to view logs to fix firewall problems or potential assaults.
- Security policies: Establish strong, enforceable security policies for your firewall.

Vulnerability assessment is a process for finding target faults. In this case, the organization is aware that its systems or networks have defects or weaknesses, and they want to identify these flaws and prioritize them. Meanwhile, penetration testing is a process for finding vulnerabilities. In thiRead more
Vulnerability assessment is a process for finding target faults. In this case, the organization is aware that its systems or networks have defects or weaknesses, and they want to identify these flaws and prioritize them.
Meanwhile, penetration testing is a process for finding vulnerabilities. In this scenario, the firm would have installed all security precautions they could think of and would wish to investigate any more vulnerabilities in their network or system.

CIA stands for Confidentiality, Integrity, and Availability. Businesses often use CIA models to direct information security policy. Confidentiality Only authorized personnel should be able to access and view the material. Strong encryption protects the data so that even if a hacker obtains it, theyRead more
CIA stands for Confidentiality, Integrity, and Availability. Businesses often use CIA models to direct information security policy.
Confidentiality
Only authorized personnel should be able to access and view the material. Strong encryption protects the data so that even if a hacker obtains it, they won’t be able to comprehend it.
Integrity
Integrity guarantees that unauthorized individuals cannot corrupt or modify data.
Availability
The data must be available to the user whenever they need it. Availability is crucial to address network bottlenecks, regular upgrades, data backups and recovery, and device maintenance.

See lessWhat distinguishes HIDS and NIDS from one another?
Both HIDS (Host IDS) and NIDS (Network IDS) are intrusion detection systems that find intrusions. Programmers employ the HIDS on a specific host or device — the only distinction. It keeps an eye on a device’s suspicious system activity and traffic. However, NIDS is configured on a network. It keepsRead more

It keeps an eye on a device’s suspicious system activity and traffic. However, NIDS is configured on a network. It keeps track of every network device’s traffic.
See lessDescribe traceroute. Why is it employed?
A traceroute displays a packet’s path. It lists every location the packet passes through, primarily routers, especially when a packet doesn't get to its destination. Finally, traceroute helps you determine where the connection drops or breaks.

See lessDescribe the three-way handshake.
A three-way handshake is a procedure used in a TCP/IP network to establish a client-host connection and exchange packets. Here’s the three-step procedure: The client sends an SYN (synchronization) to check for available ports and whether the server is online. If the client has open ports, the serverRead more
A three-way handshake is a procedure used in a TCP/IP network to establish a client-host connection and exchange packets. Here’s the three-step procedure:
- The client sends an SYN (synchronization) to check for available ports and whether the server is online.
- If the client has open ports, the server will send an SYN-ACK message.
- The client acknowledges the message and returns an ACK(Acknowledgment) packet to the server.

See lessHow is encryption different from hashing?
Hashing and encryption change one type of data into another. Encrypted data can be decrypted and converted to the original, while hashed data cannot be reconverted.
