Secure Remote Access: How to Minimize Risks

Written by . Posted on: at .

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

Multi-factor authentication requires users to verify their identity using 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 peace of mind that an authorized user is who they say they are. Because of this, MFA is a much more effective way of protecting systems than just a username and password.

How MFA fights common cyber attacks

The main aim of cyber attacks is to obtain user 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 does manage to steal a username and password, it’s unlikely they can also compromise the additional authentication factor required for MFA. That’s why MFA is perfect Countering cyber attacks such as:


Phishing attacks are very common and usually very successful when the user hasn’t set up MFA. However, if the user has some form of multi-factor authentication, a hacker cannot access their account even if they are fooled by a phishing email. This is because a phishing email does not provide the other authentication factors that MFA requires, such as B. One-time passcodes, fingerprints, etc.


Keyloggers can capture virtually any password typed into a system. If a user has MFA enabled, just gaining access to the username and password is not enough for the hacker. When MFA is set up with a mobile authentication app, the authorized user needs that specific mobile device to sign in and authenticate the request. Without access to this device, cyber criminals cannot log in, even if they have keyloggers installed on their system.

Credential stuffing

MFA is effective when it comes to credential stuffing attacks. Credential stuffing is when cybercriminals automatically and simultaneously try a list of stolen usernames and passwords across multiple websites. Because MFA requires additional information for authentication and sign-in, hackers cannot access your accounts.

Brute force attacks

Cyber ​​attackers try to find a username and password using brute force attacks. However, 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

In MITM attacks, a hacker or malicious program interferes with the interaction between users and applications and collects information entered by the user. Ideally, MFA requires users to provide credentials from another device. This can prevent hackers from intercepting or tampering with the communication between the user and the authentication since they would not have access to this MFA device.

Many of these attacks are very common for cybercriminals in today’s world as remote working has increased since the COVID-19 pandemic. To reduce your vulnerability, consider adding two-factor authentication to your accounts to prevent account takeover. Two-factor authentication should be viewed as an investment in security, not an inconvenience. The more measures you take to mitigate your vulnerability, the better protected you and your assets are.
