Developing Secure Web Apps: How
Do You Do It?
A few fundamental practices can help
your web app be more secure, like hashing and salting passwords and correctly
implementing SSL certificates. But there are also other, lesser-known practices
that will give your app an edge in the marketplace. Continue reading to learn
about some recommended methods for creating a more secure web application.
What Are the Best Practices to Develop Secure
Web Apps?
A few fundamental practices can help
your web app be more secure, like hashing and salting passwords and correctly
implementing SSL certificates. But other lesser-known practices will give your
app an edge in the marketplace. Here are some recommendations for making a more
secure web app:
Ensure HTTPS
The primary way to mitigate specific
attacks is to use HTTPS for your app. Historically, many websites were not
configured to use SSL encryption and were susceptible to various types of
"man in the middle" attacks. An attacker intercepted communications
between a client and server, altered messages, and retransmitted them. To
prevent these attacks, web app, developers should strive to use secure HTTP
connections to their servers by configuring their web servers to support SSL.
Warn Users When Their Passwords are Hashed
Passwords should be hashed before
being stored on a server to avoid XSS attacks since hashing scrambles all or
part of the password, making it unusable as a method of authentication. To
guard against the possibility of attackers brute-forcing the original passwords
from the hashes, it's best to slow down hashing by using a lengthy hash
algorithm that requires more processing time.
Link Only to Authentic HTTPS Sites
At least one major security
vulnerability was born from an innocent link on a Facebook user's wall. In
2010, a known hacker used a script to create a page that looked like Facebook,
and it was hosted on one of the social network's servers. The page included
links to the profiles of other Facebook users, and when those users clicked on
them, the malicious links would redirect them to new pages created by the
attacker.
Don't Overlook Session Management.
Because attackers often exploit
stolen session cookies to access a victim's account, session management is an
essential part of web app security. Session tokens should be unique,
non-guessable strings, and they should be secured using SSL so that attackers
can't hijack them on the open Internet.
Protect Against Cross-Site Request Forgery
Attacks
CSRF attacks are the kind of attacks
that a user can unwittingly launch themselves. In CSRF, a victim's browser is
tricked into sending requests to another web server, which acts as if the
request came from that user because it has already been authenticated. This
sort of attack is often used to update a victim's account information on a
social network or bank website by deceiving a victim into clicking on a link in
an email or instant message.
Keep Session Cookies Short and Secure
Cookies are another type of id that
web developers can use to ensure that a user is authenticated. However, if an
attacker can hijack a cookie sent by the victim, they can create their session
state and continue to access the account. To prevent this type of attack, you
should set the session cookie's expiration time to one minute or less
(developers can usually configure cookies to expire after a certain amount of
inactivity) and use encrypting cookies if necessary.
Be GDPR Compliant
One area where web app developers
don't get enough attention is the subject of data privacy. GDPR
compliance means that companies face
fines of up to 4% of their global yearly turnover if they have mishandled
personal information such as emails, phone numbers, names and addresses.
Therefore, the most critical GDPR practice is ensuring that any personal data
is appropriately stored and protected with robust encryption methods so that
unauthorized parties can't access it.
What is Cyber Insurance?
Cyber Insurance covers many
cyber-related issues such as data breaches, computer virus attacks, denial of
service (DOS) attacks, hardware failure and software malware. Cyber insurance is essential for businesses that want to protect their client's data
and their own as well. Companies that deal with significant volumes of credit
card information, social security numbers, and other sensitive data should
consider cyber insurance coverage. A cost-effective solution to receive the
cyber-attack protection you need is Cyber Insurance. It complements ordinary
insurance that all firms should have to safeguard their technological
investments and operations.
Conclusion
Web applications serve as the primary
entry point for hackers to exploit and wreak havoc worldwide. These apps share
a common weakness – their users. Web app developers are responsible for
ensuring that their apps are not vulnerable, but the users themselves need to
be educated about these threats and how to avoid them.
