Hacking and Security

§  This is a story that is concerned with a young man (thirteen years old) who attacked the GRC.com website. The website belongs to a giant research corporation. The CEO of that corporation is Steve Gibson. On March 4th evening of 2001, the GRC website went down. Gibson found out that his corporation was hacked by a little kid so he did the best he could to track him and catch him. At the end, Gibson was finally able to catch him and stop what he did.



§  Windows PC’s were unable to send TC PSYN packets to pot 80 and were only able to flood them with UDD and LCMP packets (Which could be temporarily ignored)  ISP was able to filter their receipt of the malicious packets before they were able to reach their T1 trunks. TCP – based services ( web/ FTP news) offered even under continuing attack.


·         ATTCKS WERE 474.
·         ATTACKED BY 474 Windows PC’S and a machine per piece wich means 474 machines with multiple domains.


·         Hackers referring to various lists of “cable Bots” and saying things like “ Heh, but now many of this Bots are cable?” are a remote control of Zombie.

·         Eight machines used in the attack.




Regarding the statement, I would say that I agree.

·         A better security should be provided.
·         The Internet security intervention should be prevented by putting a law for judging those people and giving them harsh punishments.





Sub 7 Server: Grants the hacker who is controlling the Zombie, the “ Zombie Master”  - absolute control over his victim’s machines.

Sub 7Server Torjan enables is monitoring every keystroke for the purpose of capturing anything online such as, passwords, credit cards, eBanking …etc.

Zoho's winning strategy: open source + cloud

Open source are known to be applications that promote access of materials available for free to the users. The internet is the environment that we find those open source applications. Some examples of those are Google Docs and Zoho.
The term Cloud means or refers to the process of transferring data between different devices through the global internet connection. The significance is shown in the case when a user purchases a program or an application, by using a Cloud, you don’t have to purchase it in order to use it on another device. The idea is that the storage space will be located on the internet instead of saving the files on your computer. In this case, the user will have access to all his/her files as long as there is internet connection.
Zoho is known to be the strongest threat to Google Docs. It is as old as 13 years and it has always been free. Raju Vegesna, evangelist of the company admits the fact that in today's world avoiding open source software is almost impossible. The company is also known as AdventNet and it has around 1.8 million users in its website zoho.com. the growth rate is about 100,000 new users every month, which is great. In 2003, they managers were just deciding whether or not to go open source as Vegesna explains and they were thinking of going SaaS. At the end they opted for both.
To clarify the idea of the article, the following quote seems to be informative: "Open-source software inside with a cloud delivery strategy, and open APIs to give external developers access to that cloud". Zoho is becoming a considerable part of core of some companies’ business because they use it with their operating system, database, application server, and scaling system. The advantage of those businesses is that they can modify those open source application and adapt them to the business environment that they run. Vegesna reported, "Without open source I can't imagine SaaS [software as a service] taking off. The economics simply wouldn't work."
