What is a brute force attack? What can you do to stop it?
Brute force is a method for accessing credentials by trial and error — continually attempting all possible combinations of credentials until you hit the right one. Here’s how you can avoid brute force attacks: Maximum Length Password: Specify the maximum length of a password, so it becomes harder toRead more
Brute force is a method for accessing credentials by trial and error — continually attempting all possible combinations of credentials until you hit the right one. Here’s how you can avoid brute force attacks:
- Maximum Length Password: Specify the maximum length of a password, so it becomes harder to find the right combination.
- Password Complexity: Requiring many character types in the password makes brute force attacks more difficult. You might establish requirements for special characters, upper- and lower-case letters, and numbers.
- Limiting Login Attempts: Establish a cap on failed login attempts, which makes it impossible to try all possible password combinations.

Data leakage is a purposeful or unintentional transmission of data (private information from within the company to an unapproved outside location (unauthorized party). Based on how it occurs, we can split data leakage into three categories: Accidental Breach: When an organization accidentally sendsRead more
Data leakage is a purposeful or unintentional transmission of data (private information from within the company to an unapproved outside location (unauthorized party).
Based on how it occurs, we can split data leakage into three categories:
You can stop data leakage with DLP (Data Leakage Prevention) tools, software, and techniques.

Secure servers encrypt and decode data using the Secure Sockets Layer (SSL) protocol to prevent unauthorized access to it. Here are four fast ways to safeguard a server: Step 1: Make sure your root and administrator account passwords are safe. Step 2: Create new users to manage the system. Step 3: ERead more
Secure servers encrypt and decode data using the Secure Sockets Layer (SSL) protocol to prevent unauthorized access to it.
Here are four fast ways to safeguard a server:
- Step 4: Configure your firewall rules for remote access.
See lessHow 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.
See lessWhat distinguishes penetration testing (PT) from vulnerability assessment (VA)?
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.

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, 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.
