The Flaw Of A Computer Environment

All passwords should be promptly changed if they are suspected of being disclosed, or are known to have

One of the other failures that the book presents us is the user’s weak password practice and how the intruder took advantage of this is to gain super user privileges and created several user accounts by gaining root privileges. All it takes is a one-time access as super user to establish his base into the defenders zone. This book describes how the intruder took advantage of brute force method to hack user accounts and password. Also, the intruder was smart enough to steal the password information file and even managed to encrypt all the dictionary words by using the same encryption algorithm and then compared those words with the stolen encrypted passwords file to find out passwords of user accounts. The scientists/ researchers at the laboratories who are not aware of such kind of exploitations made intruder’s work easy by having easy to guess passwords, never bothered to change the passwords from time to time or in fact did not realize the importance of having strong passwords in order to maintain and protect their research data in a safe and secure way. Even today, not all the users realize the importance of having strong/secure passwords and we come across such instances where intruders exploit users ignorance. (For example, Two years ago, before I enrolled in MS-CS program, I did not know how brute force attacks work or

It’s the most important security feature and basic mean of authentication its important to set secure ungues sable password security is most critical means to protect a system a good password is always desireable not to be compromised the system

That anyone who could gain unauthorized access to your computer will then have all your passwords at their disposal.

The combination of the password and the complexity directly lead to its unpredictability. With 8 character complex passwords, with current GPU processing power a password can be broken in less than 26 days by exhausting all possible combinations.

The most effective way to protect your personal information on the internet is to have a strong password. A strong password should consist of a mixture of upper and lower case letters, numbers, and special characters. Ideally you want a unique password made up of at least ten characters for every website you have an account on.

Virtual Machine Security - Full Virtualization and Para Virtualization are two kinds of virtualization in a cloud computing paradigm. In full virtualization, entire hardware architecture is replicated virtually. However, in para virtualization, an operating system is modified so that it can be run concurrently with other operating systems. VMM Instance Isolation ensures that different instances running on the same physical machine are isolated from each other. However, current VMMs do not offer perfect isolation. Many bugs have been found in all popular VMMs that allow escaping from VM (Virtual machine). Vulnerabilities have been found in all virtualization software, which can be exploited by malicious users to bypass certain security restrictions or/and gain escalated privileges. ation software running on or being developed for cloud computing platforms presents different security challenges. It is depending on the delivery model of that particular platform. Flexibility, openness and public availability of cloud infrastructure are threats for application security. The existing vulnerabilities like Presence of trap doors, overflow problems, poor quality code etc. are threats for various attacks. Multi-tenant environment of cloud platforms, the lack of direct control over the environment, and access to data by the cloud platform vendor; are the key issues for using a cloud application. Preserving integrity of applications being executed in remote machines is an open

Strong Password Assignment. The password must be a minimum of ten characters in length and must contain alpha, numeric, and special characters. Default passwords should be immediately changed when assigned. Users must never reveal their passwords to anyone. Passwords should not be constructed from obvious personal data, i.e. social security number, telephone numbers, relative’s names, pet’s name, etc.

While the present exploits are using PowerPoint files to deliver the malware, given the type of flaw, they may start using different office files such as word documents or excel spreadsheets.

Often attacks are based on software bugs that a hacker can use to give himself or herself super-user status. Also one can get a copy of the password file (which stores user names and encrypted passwords and is often publically accessible) and either do a brute-force attack trying all possible combinations, or encrypt a dictionary and compare the results to see if anyone choose a password that is a dictionary word.

The article, “Why Software is So Bad”, by Charles Mann explains the difficulties and problems of programming software which contributes to our everyday problems. Mann brings to light the inefficiencies of programming which can lead to real-world problems. Mann’s opinions expressed in the article are ideas that I can only partially agree with. The changes companies like Microsoft are making to limit the amount of errors in code and software, are steps in the right direction but faulty code has taken lives and has put people in danger. This, in my opinion, is something that needs to be eliminated and Mann targets this area of software as he lashes out at the thirteen percent error rate (13 errors per hundred lines of code).

Passwords for access to personal phones, computers, online portals, and websites has become very prevalent and the best practice for authentication. Additionally, passwords authenticate mobile phones, computer networks and databases for many software applications. However, ensuring that passwords are encrypted, and safe have become one of the greatest challenges for most organizations. This paper will review some of the vulnerabilities of the use of passwords and provide controls to implementation to assist with the management and handling of passwords.
