...Harden Windows XP with Group Policy Brian Blanchette Strayer University Abstract Hardening client computers is essential when you are using a multi platform based network. Hardening is simply creating security lockdown protocols that will deter any intrusion from the outside and inside of a network. There are several ways to deploy those hardening settings the Security Configuration Wizard Graphic User Interface (SCW GUI), the Scwcmd command line deployment tool, and the Group Policy object (GPO). We will be discussing the GPO deployment method. This hardening procedure is required to maintain a secure operating system and network environment as a network firewall cannot prevent all intrusion that need to be stopped. When using the GPO to deploy security setting to another client computer there are some things that need to be done in order for the set up to be successful. There will be the need for a security risk assessment to be conducted to determine what will need to be protected against and what type of protection levels will need to be implemented. How the hardening (security) policies will be created and deployed to client computers. What type of operating systems is on the network in order to test the policy before it is deployed? With these question answered the hardening process can begin. First the servers and client computers must have the latest updates from their respective software company then the policies...

...increasingly difficult.” Data Security and intrusion prevention are major concern for basic system security. A good backup plans and techniques secures the data loss and data security, correct authentication helps in prevention of unauthorized access of system from external network and thus prevent loss of data and vital information. Locking system and password protection secures break in security issues. Protection of data and information from being theft, corruption or natural disaster is main objective of system security. The term computer system security means, the collective processes and mechanisms by which sensitive and valuable information and services are protected from publication, tampering or collapse by unauthorized activities or untrustworthy individuals and unplanned events respectively. System Security methods or design which shows different security controls are placed and how they are involved with information technology. To maintain system quality attributes like integrity, availability, confidentiality and assurance a controlled and structured security plans must be adapted.

...Lab #2: Executive Summary Windows Hardening Defense, starts with the basics, Log in with least amount of privileges. Always use Firewall and AV. Monitor channels for security advisories and alerts. Know your system(s). Patch early and patch often, Unpatched Systems are the lowest of low hanging fruit. Have a patch policy documented and stick with it. Review patches as they are released and determine criticality based on the exploit, threat footprint for your system(s), and whether or not there is a POC or fully weapon exploit in the wild. When possible, test patches before rolling out in production on servers. Most clients should have automatic updates enabled for the OS and any application listening on a socket or used with untrusted data (java, adobe, browsers, etc...) Servers should be updated during maintenance windows if possible and depending on criticality (of threat and server).

...It is very important to go through the process of hardening your network. Hardening is where you change the hardware and software configurations to make computers and devices as secure as possible. I choose the network layout workgroup. First with the workstations and laptops you need to shut down the unneeded services or programs or even uninstall them. I would also have installed reputable anti-virus software on the workstations. You also need a hardened image for all of your workstations. To do this you need to install a new copy of the operating system and then begin the process of hardening it. After you have one good hardened workstation you can use it as a model for all other workstations and laptops. As for the router you definitely need to protect it from unauthorized access. The router needs to be password protected and you should periodically change that password for added protection. For the cable modem you should keep all unwanted and unused ports closed. I would also schedule a regular scan of all the systems as part of my maintenance processes. These processes and procedures apply for all hardware devices. Disable remote administration, administration of your router / access point should be "local only", namely, there is no reason to let people from another country have access to your network hardware and If you need to make changes, you should be local to the device. Update the firmware. Believe it or not, consumer network hardware needs to be patched also. Check...

...I chose hardening Windows Server 2008. Building a hardened server should begin from the start of its implementation. If at all possible the new Windows Servers should be installed on an isolated network. This will keep it from being attacked before the operating system is hardened. Increasing the security of your servers will effectively minimize many vulnerabilities and threats. The chances of your system being compromised after the implementation of your hardening methods will be greatly decreased. There are things that you can use to ascertain what your security posture is and then go from there to see what you need to do to harden your system. The Microsoft Baseline Security Analyzer (MBSA) is a tool that will provide an assessment of your Windows Server 2008 security configuration....

...Date: Instructor: Riordan’s Windows Server and Linux Critique At the request of Riordan Manufacturing, Inc., the project team conducted a thorough review to compare the advantages and disadvantages of Windows Server and Linux. The recommendation of an operating system will ensure Riordan’s business operations continue with compatibility between all locations with the highest level of security, administration, networking, performance, and programmabilityimplemented. Security Although there are proponents everywhere for each type of operating system available on the market today, the focus of this project team, at the request of Riordan management, is to compare the security advantages and disadvantages of Windows Server and Linux. Windows Server Advantages. Windows Server has improved over the years in providing basic security provisions for administrators. Access to any system is extremely important to security professionals, such as domain name system (DNS), active directory domain services (AD), and access to web servers using Internet Information Services (IIS). DNS security extensions (DNSSEC) provide added security when a consumer is gaining access to a company’s website as well as how the company interacts with the consumer securely. In relation to AD, authentication for end users within a company to gain...

...IT-255 unit 1 assignment 2: impact of a data classification standard Hello everyone at Richman investments, I was s asked to write a brief report that describes the "internal use only" data classification standard of Richman investments. I will list a few of the IT infrastructure domains that are affected by the standard and how they are affecting the domain and their security here at Richman investments. * User domain The user domain defines the people who access an organizations information system. In the user domain you will find an acceptable use policy (AUP). An AUP defines what a user can and cannot do with organization-owned IT assets. It is like a rulebook that the employees must follow. Failure to follow these rules can be grounds for termination. The user domain is the weakest link in an IT infrastructure. Anybody who is responsible for computer security understand what motivates someone to compromise an organization system, application, or data. Now I am going to list risk and threats commonly found in the user domain and plans you can use to prevent them. Lack of user awareness - solution - conduct security awareness training, display security awareness posters, insert reminders in banner greeting, and send email reminders to employees. Security policy violation- solution - place employee on probation, review AUP and employee Manuel, discuss during performance review. Employee blackmail or extortion- solution - track and monitor abnormal employee behavior...

...The User Domain defines the people who access an organization’s information system. One of the roles and tasks is that the user can access systems, applications, and data depending upon their defined access rights. Inside the User domain is where the user would find the acceptable user policy or AUP. The AUP defines what users are allowed to do within the organization-owned IT assets. The User Domain is considered the weakest and most affected domain. One reason why is that it has a lack of user awareness. Another reason is that when users are downloading various content and different files, they generally do not conform to the established security guidelines. To protect from these issues, there should be enabled content filtering as well as automatic antivirus scans. A way to protect from an user doing Employee blackmail or extortion is to enable intrusion detection system/intrusion prevention system (IDS/IPS) monitoring. The monitoring will examine the IP data streams for inbound and outbound traffic. A second domain that is affected is the Workstation Domain. The Workstation Domain is where most users connect to the IT infrastructure. A workstation can be a desktop computer, laptop or any device that connects to the network. A role of the workstation domain is that the organization’s staff should have the access necessary to be productive. Some tasks included are configuring hardware, hardening systems, and verifying antivirus files. Threats that are included in the Workstation...

...be countered or prevented. When the university suffered an overwhelming internal DDoS attack, it required administrators to reevaluate its security guidelines based on what was known about the attack. As seen at the time of attack, certain characteristics were: Network performance unusually slow Website was unavailable for at least 24 hours Thousands of bogus HTTP packets sent to internal web server Taking these factors into account, it can be safe to say it was an actual attack rather than just legitimate network usage. Now that it is known what such an event would look like, identifying similar attacks in the future will be much easier and may allow for limited down time. Deployment of an Intrusion Detection or Prevention System Implementing the installation of an IDS or IPS will allow for suspicious traffic to be flagged and reported to administrators based on one of two different factors. These factors are signature based or anomaly based depending on how they are configured. These devices should be installed wherever essential...

...due at the beginning of class the following week. Students are encouraged to perform and submit their lab assessment results immediately upon completion of the lab activity or prior to the due date. During this lab students will properly secure a Linux server system. They will perform steps to secure the bootloader, enable iptables and run SELinux to help lock down the Linux OS. The students will also apply ACLs to directories and files and then check those ACLs and permissions on the system. To accomplish the lab assignment below, students will need to obtain a copy of the Fedora Image provided to you by the Substitute Instructor and complete a basic VMware installation of Fedora. The questions in the lab book will be based on the installation experience. Assigned Pages: 10-26 Questions: 1 through 10. This assignment is due by the beginning of class for Unit 3. 1. What is GRUB and why is it important to lock it down? GRUB stands for Grand Unified Bootloader (1 of 2 boot menus' for the operating system) which is important to lock down is for security reasons. These reasons include being used to start other operating systems (eg. other versions of Linux or Microsoft Windows), & can be used to boot a system into single-user mode with full administrative privileges. 2. Discuss the purpose of granting "sudo" access. Why is it a good idea not to login as a root user? The "sudo" (-su or -sg) command logs the user in as root administator which is dangerous & why...
