Secure Remote Access: How to Minimize Risks

Published by . Posted in: in .

As we know, traditional single-factor authentication systems require users to only provide a username and password to access a network or system application. A username and password are easily accessible for a hacker to steal and gain access to your security system.

Multi-factor authentication requires users to verify their identity with two or more factors (something you know, like a password, something you have, like a physical device, and something you are, like a fingerprint). Sonicwall MFA provides reliable assurance that an authorized user is who they say they are. This is why MFA is a much more effective method of protecting systems compared to just a username and password.

How MFA combats common cyber attacks

Cyberattacks mainly consist of obtaining a user’s account credentials. Multi-factor authentication requires users to provide additional information or credentials beyond a username and password to gain access to an account. Even if an attacker succeeds in stealing a username and password, it is unlikely that he or she will also be able to compromise the additional authentication factor required with MFA. That’s why MFA is perfect in combat cyber attacks What:

Identity fraud

Phishing attacks are very common and most of the time very successful when the user does not have MFA in place. However, if the user has some kind of multi-factor authentication, even if they are fooled by a phishing email, a hacker will not be able to access their account. This is because a phishing email does not provide the other authentication factors that MFA requires, such as one-time passcodes, fingerprints, etc.

keyloggers

Keyloggers can capture virtually any password that is entered into a system. If a user has MFA enabled, then it is not enough for the hacker to gain access to just the username and password. If MFA is configured with a mobile authentication app, then the authorized user needs that specific mobile device to log in and authenticate the request. Without access to that device, cybercriminals cannot log in even if keyloggers are installed on their system.

Credential Filling

MFA is effective when it comes to credential stuffing attacks. Credential stuffing is when cybercriminals automatically and simultaneously test a list of stolen usernames and passwords across multiple sites. Because MFA requires additional information for authentication and login, hackers will not be able to access your accounts.

brute force attacks

Cyber ​​attackers will use brute force attacks to try to find a username and password. But because they don’t know or don’t have the other authentication factors required by the MFA system, they can’t access the account.

man in the middle attack

MITM attacks are when a hacker or malicious program inserts itself into the interaction between users and applications and captures the information that users enter. Ideally, MFA requires users to provide credentials from a different device. This can prevent hackers from intercepting or manipulating the communications between the user and authentication, since they would not have access to that MFA device.

Many of these attacks are very common for cybercriminals in today’s world as there is an increase in remote work since the COVID 19 pandemic. To lessen your vulnerability, you may want to add two-factor authentication to your accounts to prevent appropriation of the account. Two-factor authentication should be viewed as an investment in security and not as an inconvenience. The more steps you take to minimize your vulnerability, the more protected you and your assets will be.
