Secure file transfer protocols like SFTP and FTPS are essential for protecting sensitive information during file transfer. SFTP (SSH File Transfer Protocol) and FTPS (File Transfer Protocol Secure) both use encryption to secure data during transfer. SFTP uses SSH (Secure Shell) to encrypt data, while FTPS uses SSL/TLS (Secure Sockets Layer/Transport Layer Security) encryption. Both protocols require a username and password to access the files, and they can also support multi-factor authentication for added security.

Social Engineering Awareness

Social engineering is a tactic used by hackers to manipulate individuals into divulging sensitive information or performing actions that compromise security. This can include tactics such as phishing emails, phone calls, or even physical impersonation. It is important to be aware of these tactics and to never give out personal or sensitive information unless you are certain of the legitimacy of the request. It is also important to regularly update passwords and to use multi-factor authentication whenever possible to protect against social engineering attacks.

Recognizing Social Engineering Tactics

Recognizing social engineering tactics can be challenging, as they often involve manipulation and deception. However, there are some common signs to look out for. One tactic is urgency or pressure, where the attacker creates a sense of urgency or panic to get the victim to act quickly without thinking things through.

Another tactic is authority, where the attacker poses as someone in a position of power or authority to gain the victim’s trust and compliance.

Practising Caution With Sharing Personal Information

It is also crucial in preventing social engineering attacks. Attackers may try to gather personal information about their victims through various means, such as phishing emails or phone calls, to use against them in future attacks.
