Those ports and their vulnerabilities are frequent targets as well, but the three that rank at the top based on research from Alert Logic are ports 22, 80, and 443. Port 22 is SSH (Secure Shell), port 80 is the standard port for HTTP (hypertext transfer protocol) web traffic, and port...
1 Introduction It is a commonly held belief in the security community that safety violations such as buffer overflows are unprofessional and even downright sloppy. This recent quote =-=[33]-=- is typical: Common errors that cause vulnerabilities — buffer overflows, poor handling of unexpected ...
A bounty is offered for vulnerabilities, see the VULNINFO.md file for more information. This project uses safe functions likesafe_strcpy()instead of unsafe functions likestrcpy(). This project has automated unit regression tests (make regress). ...

An alternative way to obtain the IP addresses and ports associated with the Apache server is to utilize the nmap command. Nmap is a powerful open-source tool for network exploration and security scanning, providing insights into device discovery, open ports, and vulnerabilities. Additionally, commonl...
As a more specific example, attackers sometimes attempt to exploit vulnerabilities in the RDP protocol by sending attack traffic to port 3389. To stop these attacks, a firewall may block port 3389 by default. Since this port is only used for remote desktop connections, such a rule has little...
Port 8080: Often used as an alternative to port 80 for HTTP traffic, especially when port 80 is already in use. Port 143: Used for Internet Message Access Protocol (IMAP) traffic, which is used for accessing email on a server. Port 389: Used for Lightweight Directory Access Protocol (LDA...
be accessible from outside the corporate network. If not, security admins should shut them down or block them. If the open ports are deemed necessary, admins should begin to research what vulnerabilities and exploits the network is open to and apply the appropriatepatches to protect the ...
An Open Port Checker Tool is a software or online service that allows users to scan and check if specific ports on a target system are open or closed. It helps identify which ports are accessible from the internet and can provide information about potential vulnerabilities. ...
HTTP (80) Assigned to web servers and directly associated with the Hypertext Transfer Protocol. POP3 (110) POP3 or the Post Office Protocol is used by email clients to retrieve data from remote email servers. SFTP (115) SFTP or Secure File Transfer Protocol, is a separate protoco...
