Practices to Secure Java Secure Java Secure Java Programs
Use parameterized queries
Many attackers easily infiltrate databases using sql injection attacks on backend databases of any java applet, to prevent this use sql queries that are parameterized so that any malicious user cannot input special characters in order to perform the attack.
Scan dependencies for loopholes
Many data breaches occur due to outdated applet dependencies, so make sure that all of the dependencies and libraries are updated with the latest security patches, if any released.
Use input sanitization
Mishandling of input may lead to xss attacks, so always make sure that only trusted input is passed to the server.
Properly configure xml parsers
XML parsers used in java applets are vulnerable to xxe attacks in which malicious xml entities are injected into the applet. Always make sure that you disallow external entities and allow only entities having defined format.
Don’t use java deserialization
Use strong encryption and hashing algorithms
W3hile storing or transmitting data, always make sure you use proper encryption algorithms to encrypt or encode your data to protect it from data breaches.
