Cracking the Code: Defending Against Application Layer Attacks

In today's fast paced world Network security holds an imminent concern for many reasons. Data security and sensitivity is a big challenge across the globe.

Firstly, we need to protect sensitive data, preventing unauthorized access and potential breaches, ensuring the confidentiality and integrity of critical information.

Secondly, robust network security measures bolster the trust of users and clients, establishing a foundation for secure online interactions.

?

Thirdly, mitigating the risk of financial losses and reputational damage associated with cyberattacks, providing a safeguard for businesses and

organizations. Moreover, network security is pivotal in maintaining the uninterrupted flow of operations, preventing downtime caused by malicious activities.

?

Finally, in this complex interconnected world, where digital threats are kept increasing, investing time and learning network security is an essential proactive measure to adapt and fortify against emerging cyber risks.

However, it is essential to understand the network threats comparing with OSI layers, I know many of us don’t like the technicalities, but if the threats are technical manipulated thus we need to understand and cope with it.

?

Have you ever heard about OSI layer ?,

The old ditch layers. Excuse me for my wordings, in fact OSI layers are always come with some dizzy thoughts.

Let me share stuff for the Application Layers, by OSI layer, it would be the 7th layer consisting of the applications arenas like docs, word, power-point, browser and many more.

There are several threats to application-layer like “Malware and Viruses”, which are defined as Malicious software designed to disrupt or damage applications and data.

Prevention to be taken from the updated antivirus software, regularly scan for malware, and email filtering.

?*SQL injection.

It is designed and developed to exploit vulnerabilities in database queries to gain unauthorized access or manipulate data.

Prevention: Security engineers need to Validate and sanitize input data, use selected queries, and implement least privilege principles.

*Cross-Site Scripting.

It is formulated to create injecting malicious hidden unknown scripts into the web-application, which could be anywhere, it could be in games or any online apps.

How to prevent them: simply avoid using application, avoid plugins, only use valid websites for work or other activities.

*Cross-Site Request Forgery.

In this attack, users are being forced to do unintended actions like installation/uninstallation etcetera without user’s knowledge or awareness.

Solution: use good antivirus and make it updated, use Anti-CRF token, you can use desktop firewall as well.

*Session Hijacking.

Unauthorized users like Hacker always interp the session take control user internet traffic e.g internet browsing etcetera.

Solution: Use desktop firewall and try to use two-way factor authentication or multifactor authentications.

*Brute-Force:

Hackers are trying to gain access by multiple attempts to the target.

Solution:? account locked after 3 attempts.

Zero-Day Exploits.

Attacker is focused to exploit the software or Operating systems vulnerabilities to target them.

Solution: use valid desktop firewall, anti-virus software and kept updated on daily or weekly basis, however, the OS should be updated in timely manners.

?

Conclusion: it is often seen that most of the professionals are using cracked software/tools, by using this they are opening doors for attackers/hackers.

Most of the cracking sites are infected and banked with malware and viruses. *Try always to buy genuine software, you may check it, it will be all secured. ?

Hackers have always some agenda to get into, reach out to your previous information like credit card or personal information by snooping into your personal computers.

If you install any crack software, windows OS, always tend to say, it has some virus, but we always ignore it and that is how are strengthening the Hackers. ?

?

Remember your data and your privacy is more precious than the software, so please avoid cracked software.
