Hello everyone,


Network security has always been the top priority of the Internet. The rapid development of network technology, not only brings convenience to people but also makes network security risks more and more serious. 


Launching network attacks has become easier and cheaper, and the impact caused by them is getting bigger and bigger. Common network attacks in life are Trojan horse, DDoS attack, ARP attack, phishing, etc.

Whether via the spread of malware, spyware or viruses, insiders can do as much damage as outside attackers, 10 ways to prevent computer security threats from insiders.

1. Security policy first
2. Don't neglect physical security
3. Screen new hires
4. Use strong authentication
5. Secure your desktops
6. Segment LANs
7. Plug information leaks
8. Investigate anomalous activities
9. Refocus perimeter tools and strategies
10. Monitor for misuse

It's not just malicious actors, either. Employees can unwittingly sabotage systems and create computer security threats through sheer ignorance. Simple mistakes such as clicking rigged links in emails, messaging apps and advertisements invite hackers to surveil companies and organizations with massive consequences.

Network security typically consists of three different controls: physical, technical and administrative. Here is a brief description of the different types of network security and how each control works.

Physical Network Security
Physical security controls are designed to prevent unauthorized personnel from gaining physical access to network components such as routers, cabling cupboards and so on. Controlled access, such as locks, biometric authentication and other devices, is essential in any organization.

Technical Network Security
Technical security controls protect data that is stored on the network or which is in transit across, into or out of the network. Protection is twofold; it needs to protect data and systems from unauthorized personnel, and it also needs to protect against malicious activities from employees.

Administrative Network Security
Administrative security controls consist of security policies and processes that control user behavior, including how users are authenticated, their level of access and also how IT staff members implement changes to the infrastructure

Yes for sure, at my work place was phishing mail 33% among all.
Note: it was testing by IT security team

My experience - Insider threats Top 4 real world insider threats are:

-1- Complacency or "good intentioned" insiders - bypassing security policies in order to expedite a task.(we have all done it ) but many times these one time use emergency tasks that should be approved by security and done under the table and become the unwritten SOP for departments.

-2- A non-technical VIP being granted higher level permissions then needed, and to be blunt a dangerous level of permissions for their skill level, leading to security policies violations , leading to a compromise. a common example is a PM managers being granted full System admin rights to his departments email, SharePoint, database servers, etc. If his/her account is compromised the company network is at high risk.

-3- Management overriding good security practices to complete a task due to project resource or time limitations. This will almost always lead to a repeated violations, and adds risk to the security of the organization.

-4- The number one security threat that I have seen over the last 15 year in Cyber security is :
Misuse ( abuse) of elevated accounts. largely from lower level techs using admin accounts to perform lower level functions. an example : NEVER go to the internet while logged into a device with an admin account.

So we should keep the super account password safe. Avoid loss and leakage. The administrator must change the password periodically to ensure password security.
