Sophos Firewall offers protection against Denial of Service (DoS) attacks primarily through its rate limiting and anomaly detection features. Rate limiting helps to control the volume of traffic that is allowed to reach the network, ensuring that no single user or source can overwhelm the system by sending an excessive amount of data. This essentially sets a threshold that must be respected, effectively mitigating the impact of a DoS attack by preventing these malicious traffic bursts from consuming all available network resources.

Anomaly detection complements this by identifying unusual patterns of traffic that may signify a DoS attack in progress. This proactive monitoring allows the firewall to automatically respond to potential threats by blocking or filtering traffic that deviates from normal behavior. Consequently, this combination of rate limiting and anomaly detection is integral in maintaining the availability of services against flooding and other types of DoS attacks, ensuring that legitimate users can still access resources during an attack.

In contrast, restricting user access, while useful for managing who can connect to the network, does not fundamentally guard against DoS attacks, which target the capacity of the network infrastructure. Increasing bandwidth allocation can provide temporary relief but does not address the root of the problem, as attackers can simply ramp up their efforts to fill the increased capacity.
