Internet security
- 1. RECENT TRENDS IN TECHNOLOGY & INTERNET SECURITY
- 2. Introduction • Operating System • Websites • Passwords • Hackers • Mobile Platform • Virus & Worms • Recent Trends • Bio metrics
- 3. Unix / Mac OS /OS X • Unix (all-caps UNIX for the trademark) is a family of multitasking, multiuser computer operating systems that derive from the original AT&T Unix, developed in the 1970s at the Bell Labs research centre by Ken Thompson, Dennis Ritchie, and others • Permission technology and also the user groups sandboxing. • Root / superuser sandboxing • Virus adaptability better than its competitors.
- 4. Windows • It is the most commonly used OS world wide. • It was developed by Microsoft • It uses DLL and registry model. • It uses a user access control system.
- 5. Linux • Linux is a Unix-like and mostly POSIX- compliant computer operating system assembled under the model of free and open-source software development and distribution. The defining component of Linux is the Linux kernel,an operating system kernel first released on 5 October 1991 by Linus Torvalds. • Almost all the security measures of that of Unix. • Ubuntu • Mint • Fedora • Red hat
- 6. WEBSITES
- 8. PASSWORD
- 9. Password • Its a simple mechanism to know whether the user is genuine • It may include letters numbers and may be in some cases the special characters • Password of the future may include the physical verification • extended security through 2 step verification. • Password mangers to help you for password management
- 10. Precautions for password • Different password for each and every website • Avoid managers but too many passwords mean managers • Use long passwords and avoid 123456, Password , Incorrect etc • Avoid using meaningful words. • use multilingual password • Enable 2 step verification for the Gmail iCloud and available services • Enable notification for Facebook and authenticators for generating a 2nd layer security.
- 11. • using passwords like these would ensure your computers are safe but as said earlier MEMORY? • Change the password in every 72-90 days • Make sure you log out of the online services after use. enable auto sign in the computers you have complete control on. • enable guest users for the computers and for mobiles . • use incognito mode when ever you want your searches traceless • Clear the cookies and the history every 2 months. • Avoid auto login saves time but your safety?
- 12. MOBILE PLATFORM
- 13. iOS • iphone os - iOS • Developed based on unix • used by apple closed coded • Benefits of sandboxing • limitation slow roll out of features • Fast updates
- 14. Android • Freedom • users mode • customise the appearance • easier access to the google services including the mail the contacts the calendar system • drawbacks too much resource allocation. • Hacking prone
- 15. Windows Phone • Better than windows mobile • Fast growing • Benefits of the existing users • easier to learn for the majority of the users • hugely inspired the windows 8/8.1 and the windows 10
- 16. • There are other Mobile OS available like ubuntu, sailfish, Tizen and many more. • But then why is it that they are not popular? • Not well developed App stores - the hardware companies want to go with the tried and tested • the os will require a specific hardware and • best is already used.
- 17. HACKERS
- 18. – Fred Durst “If you wanna know how not secure you are, just take a look around. Nothing's secure. Nothing's safe. I don't hate technology, I don't hate hackers, because that's just what comes with it, without those hackers we wouldn't solve the problems we need to solve, especially security.”
- 19. Black Hat Hacker • Dont follow rules • Doesn't do hacking for approved reasons • Malicious codes / virus • Violates computer security
- 20. White Hat Hackers • Computer Security • Improves Security and Services • Hacks with the permission of the user.
- 21. Hactivists • The story of Anonymous • The NSA • The Digital Terrorism. • Does Good / Bad
- 22. VIRUS & WORMS
- 23. Virus • A program that can replicate by itself and can spread from one computer to another with out the input from the creator • Needs a host program • The purpose for the virus can be different or it can be used for any purpose eg kali linux payload management
- 24. Computer Worms • It is similiar to virus and can replicate through network • It is a self sustaining program doesn't need to be attached with any of the programs • Common symptoms include overall sluggishness in the os and the slowness in the network due to increase bandwith consumption.
- 25. Trojan Horse • One of the most irritating programs in the computer world. • Inspiration from the TROY story • Does something entirely different from what it is suppose to do tricks the user. Started as a greeting card virus. • Commonly used to hack and steal information from the users commonly used in keyloggers. Hence it is called social engineering toolkit.
- 26. Types of hacking • Password cracking : it can be done in 2 ways through brute force or through dictionary guessing. • Packet sniffing : all information through the internet always passes through as packets and thus softwares like wireshark can sniff the packet data and hence get the information • Phishing : My most favourite method of hacking because requires very less work and then fool the customers into giving their information. CLONING the website.
- 27. Types of Hacking • Rootkit: Software that can hid the unwanted process from seeing in the windows task manger. • Key loggers : if you have access to the computer installing a key loggers can provide all that is typed in that computer. taps in to the typing in the computer. • Scareware/ransomware: Commonly disguise as an antivirus making you pay for the security or for providing information. Credit card informations !!! • IP spoofing / MAC address cloning : use the id of some other person and avoid being detected in the hacked network to avoid the forensic detection.
- 28. Free advice • Always protect your system with an antivirus !!!!!!! and keep it updated. • use cloud antivirus • never use a cracked system or a cracked antivirus. • it affects your motherboard and also your security.
- 29. RECENT TRENDS IN THE TECHNOLOGICAL FIRMS
- 30. Who wants 1 device ? • Apple with iPod, iPad ,iPhone, mac, apple tv car play home kit and apple watch. • Google with chrome books chrome cast android and other services like the google glass and even internet itself- project loom android wear • Windows with laptops, phones,xbox surface tabs and surface TV and Zune players, Office. • All want not one device but your complete home and the complete ecosystem • the maximum effects come with the maximum devices
- 31. Continuum - Windows 10
- 33. Self driving cars of the future. - Benz
- 34. • Wireless charging • Hands free control • 3D projectors • 3D Printers - Guess what chicken of the future will be printed. • Robotic skeletons for army. • Control the home from Anywhere in the world through Home kit. • Free and wireless payments through NFC.
- 35. BIO METRICS
- 36. Finger Print Scanner • It is simple • uses a unique design • Much safer than the face recognition • Partial and complete recognition of the finger print • Safe place to store the data • Can carry along where ever you go • But not hack free • Sensors inaccurate to detect a finger or differentiate from an animal • Good for making authentication for the payments.
- 38. USB Tokenisation • A single usb key • No passwords • Connect the USB • Incorruptible Data ROM storage. • Best used in offices, for authentication.
- 40. iris recognition system. • the most secure in the world • error rate is high • requires very good sensors • Used for very high security measures in the military • mass usage still in testing • Checking for the possibilities for the daily usage. • inconvenient for almost daily usage.
