Describe the distinction between a cryptographer and a crypter.
A cryptographer plans or analyzes any aspect of encryption. On the other hand, a crypter deliberately disguises malware as something else, such as a useful program, to propagate it unnoticed.

- Black-hat hackers are renowned for having an extensive understanding of entering computer networks. They can create malware that allows users to access these systems. These kinds of hackers abuse their abilities to steal data.
- White-hat hackers are ethical hackers since they employ their skills for good reasons. Businesses frequently employ them as security specialists who look for and close security gaps and vulnerabilities in their systems.
- White-hat and black-hat hackers combinedly form gray-hat hackers, who search for vulnerabilities without the owner’s consent. They notify the owner if they discover any weaknesses. In contrast to black-hat hackers, they don’t use the vulnerabilities discovered.

See lessWhy do ports get scanned?
Port scanning is a technique to determine a host’s available and open ports. Hackers use it to exploit vulnerabilities, while administrators use it to check the network's security procedures. Common methods for port scanning include: Ping Scan TCP Half-Open TCP Connect UDP Stealth Scanning

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.

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.
