Cloud being the main source for any data or application these days, it is essential to maintain its security. The best security measures to be followed include:
1) Identity and Access Management(IAM):
* Implementation of Least privilege access principles all across the cloud environment and also include Multi-factor authentication.
2) Data Encryption:
* Encrypt the data that is at rest and also that is being transmitted in the cloud storage with strong encryption algorithms with dedicated key management services.
3) Network Security:
* Usage of virtual private clouds, firewalls, Access control lists, and virtual private networks for cloud operations makes them create secure network boundaries.
4) Monitoring and Logging:
* Logging and monitoring critical resources and applications and analyzing the live logs with SIEM tools is good practice for detecting threats.
5) Patch Management:
* Automating the patch management process wherever possible and keeping all the systems and applications up to date with the latest security patches is very important.
By following the above measures the cloud environment can be significantly protected from cyber threats.

A zero-day vulnerability is a weakness in a software or system that: 1. Has never been seen before (it's a "new" weakness). 2. Has no fix or patch available yet. 3. Can be exploited by attackers to gain unauthorized access or control. Think of it like a brand new key that can unlock aRead more
A zero-day vulnerability is a weakness in a software or system that:
1. Has never been seen before (it’s a “new” weakness).
2. Has no fix or patch available yet.
3. Can be exploited by attackers to gain unauthorized access or control.
Think of it like a brand new key that can unlock a door, but the lock’s manufacturer doesn’t know about it yet, so they haven’t made a new key or fixed the lock.
Implications for cybersecurity:
– Attackers can use this weakness to gain access to sensitive information or systems without being detected.
– Since there’s no fix available, organizations are vulnerable until a patch is released.
– It’s like having an uninvited guest in your home, and you don’t know how they got in or how to keep them out!
Example: Imagine a hacker finds a zero-day vulnerability in a popular email software. They can use it to read and steal sensitive emails without anyone knowing until a patch is released.
