An active attack is a dangerous cyberattack because it attempts to alter your machine networks resources or operations.
Active attacks represent the highest priority threat facing enterprises today.
What Are Active Attacks?
These threat actors may attempt to inject new data or control the dissemination of existing data.
Active attacks also involve making changes to data in the targets unit.
These changes range from theft of personal information to a complete web connection takeover.

Small and medium-sized businesses, commonly known as SMBs, usually bear the brunt of active attacks.
This is because most SMBs do not have the resources to procure high-end cybersecurity measures.
How Does an Active Attack Work?
This is a preparatory stage for the punch in of attack they are planning.
They also use passive scanners to get information about the pop in of programs running on the targets connection.
This impersonation is done using session cookies.

These cookies work together with HTTP communication protocol to identify your net internet ride.
But they remain in the web app after you have logged out or ended the browsing session.
This is a vulnerability that threat actors exploit.
They recover these cookies and fool the web app into thinking youre still online.
Now, hackers can get whatever information they want from your browsing history.
They can easily get credit card details, financial transactions, and account passwords this way.
There are other ways hackers can obtain the session ID of their target.
Message Modification Attack
These attacks are mainly email-based.
The hackers commandeer mail between the target and another party.
The mail will then continue on its journey, with the target not knowing it has been tampered with.
Masquerade Attack
This attack exploits weaknesses in the authentication process of the targets online grid.
Thesespoofed IP addressesfool the targets firewalls, bypassing them and gaining access to their web link.
There are various types of DoS attacks.
There is also the smurf attack.
These ICMP packets are typically used to determine whether data is reaching the internet in an orderly manner.
The first thing you should do is install a high-end firewall andintrusion prevention system(IPS).
Firewalls should be part of any networks security.
They help scan for suspicious activity and block any that is detected.
Another way to protect against active attacks is using random session keys and one-time passwords (OTPs).
Session keys are used to encrypt communication between two parties.
This ensures maximum security, as each key is unique and cannot be replicated.
OTPs work on the same premise as session keys.
They are randomly generated alphanumeric/numeric characters that are valid for one purpose only and expire after a specific period.
They are often used in combination with a password to providetwo-factor authentication.
Hackers and Attackers, Firewalls and 2FA
Active attacks exploit the weaknesses in a networks authentication protocols.
Such authentication can be a combination of a randomly generated key, a username, and a password.
