PREVENTING XXS ATTACKS 2
Preventing XXS attacks
It’s a type of attack that involves injecting and executing malicious client-side coding
from the browser of the victim within the legitimate application of the web. The impact of the
attack usually results in stolen session cookies, hijacking sessions, and stolen tokens leading to
the compromise to user accounts (Liu, et al., 2019). For instance, stolen cookie data can be used
to impersonate legitimate users hence compromising the pages or executing codes on the server-
side of the web application. Types of attack here include DOM-based XSS vulnerability, stored
XSS attack, and reflected XSS attack. To prevent these attacks, developers are mandated to
validate all user input data by filtering out special characters followed by encoding the output.
characters to escape include @, #, $,), and & just to mention a few.
Secondly, encoding output sinks through the validation of user input source is necessary,
because its where attackers target to inject the malicious code (Liu, et al., 2019). Thirdly,
software updates must be done regularly like say daily because attackers are always devising
ways to exploit the weak point and hence keeping your software updated means having the latest
developments in regards to the attacks. The use of client-side as well as server-side validation
forms is also critical in evaluating any form of intrusion and taking necessary action (Liu, et al.,
2019). Lastly, a firewall is super-agent in handling attackers as it enables verification and
authentications processes before allowing access. This aids greatly in blocking the attackers from
infiltrating the system.
