Internet Security
Overview of Internet and network security protocols and architectures.
Network and Internet security is about authenticity, secrecy, privacy, authorization, non-repudiation, data integrity and protection from denial of service (DOS) attacks.
In the early days of the Internet, security was not a concern so most protocols were developed without protection from various kinds of attacks in mind. The Internet is now infested with malware like worms, viruses, trojan horses and killer packets. Unprotected hosts run the risk of being seized by hackers and become part of botnets to launch even more elaborate attacks.
Careful protection of hosts in a network is therefore of paramount importance. Hosts that need not be reachable from the Internet are typically placed in a protected LAN. Hosts with reachability requirements like mail and web servers are placed in a special network zone called DMZ (DeMilitarized Zone).
Firewalls protect the different networks. Firewall functionality ranges from simple port and address filters up to stateful application and deep packet inspection firewalls that provide more protection.
In general, security policies should be as restrictive as reasonable possible. So usually something not explicitly allowed should be classified as forbidden and thus be blocked.

Cyber crime involves illegal activities using computers and the internet. It can include hacking, fraud, stalking, and identity theft. The first recorded cyber crimes occurred in the 1820s, but cyber crime grew with the rise of email in 1976 and computer viruses in 1982. There are many types of cyber crimes, and they are committed by insiders, hackers, virus writers, foreign intelligence, and terrorists. Cyber security works to prevent cyber crimes by keeping software updated, using strong passwords, firewalls, and antivirus software. The cyber laws of India address both traditional crimes that use computers as well as new crimes defined in the Information Technology Act of 2000. Cyber crime will likely continue to evolve, so cyber security remains important.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes.

Hackers
- 2. Hack-er: a person who uses computers to gain unauthorized access to data. (Wikipedia)
- 3. • Hackers spend enormous amounts of time trying to breach the security of networks, webservers, and email servers. • Specialized software is utilized to identify weaknesses, which are then exploited
- 4. 5 Terrible Things Hackers Can Do To You • 1) Cut your car’s breaks – Security specialists at the University of Washington have shown that new cars with computer systems on board can be susceptible to a hacker gaining complete control of the vehicle. • 2) Use your computer screen as a two- way mirror – Getting access to a webcam is easier than you think in fact, there are sites devoted to unsecure webcams that have been already hacked.
- 5. • 3) See you naked – Full body scanners at airports can be hacked very easily. Last year image were leaked from an airport scanner so privacy breaches are currently a current threat. • 4) Hack your email – According to abc News email hijacking could be the prelude to identity theft
- 6. • 5) get your credit card info- are you surprised? – The most commons and one of the most devastating things a hacker can do is to steal your credit card information for financial gain. – Approximately 15 million United States residents have their personal information stolen and used fraudulently each year. On a case by cases basis losses average to 3,500. How common is it? This Forbes article provides a great example.
- 7. Tips to Consider • Schedule a scan to occur every week or so on your realtime anti-malware software, during the night or at some time your computer isn’t being used. • Make sure the virus definitions for your software are up to date before a scan. Most software updates itself, but it’s good to check. • Most firewalls have what are called “Security Prompts”, which will pop up when an unknown process begins. If you have initiated a program or some action on your own, then for the most part it’s ok and you can accept it. If you have not, block it.
