Proxy server firewalls act as a middle man for user requests. Antivirus software programs such as McAfee and Symantec software locate and dispose of malicious content. These virus protection programs run live updates to ensure they have the latest information about known computer viruses. Logical security includes software safeguards for an organizations systems, including user id and password access, authentication, access rights and authority levels. These measures are to ensure that only authorized users are able to perform actions or access information in a network or a workstation. Auditing systems, track and record what happens over an organizations network.

Specific tools used in marathi network security edit network security is achieved by various tools including firewalls and proxy servers, encryption, logical security and access controls, anti-virus software, and auditing systems such as log management. Firewalls are a very basic part of network security. They are often placed between the private local network and the internet. Firewalls provide a flow through for traffic in which it can be authenticated, monitored, logged, and reported. Some different types of firewalls include: network layer firewalls, screened subnet firewalls, packet filter firewalls, dynamic packet filtering firewalls, hybrid firewalls, transparent firewalls, and application-level firewalls. The process of encryption involves converting plain text into a series of unreadable characters known as the ciphertext. If the encrypted text is stolen or attained while in transit, the content is unreadable to the viewer. This guarantees secure transmission and is extremely useful to companies sending/receiving critical information. Once encrypted information arrives at its intended recipient, the decryption process is deployed to restore the ciphertext back to plaintext. Proxy servers hide the true address of the client workstation and can also act as a firewall. Proxy server firewalls have special software to enforce authentication.

The most popular type of security token (RSAs SecurID) displays a number which changes every minute. Users are authenticated by entering a personal identification number and the number on the token. Termination Procedures: Proper termination procedures so that old employees can no longer access the network. This can be done by changing passwords and codes. Also, presentation all id cards and badges that are in circulation should be documented and accounted for. Special User Accounts: Special User Accounts and other privileged accounts should be monitored and have proper controls in place. Remote Access: Remote access is often a point where intruders can enter a system. The logical security tools used for remote access should be very strict. Remote access should be logged.

Logical security audit edit The first step in an audit of any system is to seek to understand its components and its structure. When auditing logical security the auditor should investigate what security controls are in place, and how they work. In particular, the following areas are key points in auditing logical security: writing Passwords: every company should have written policies regarding passwords, and employees use of them. Passwords should not be shared and employees should have mandatory scheduled changes. Employees should have user rights that are in line with their job functions. They should also be aware of proper log on/ log off procedures. Also helpful are security tokens, small devices that authorized users of computer programs or networks carry to assist in identity confirmation. They can also store cryptographic keys and biometric data.

Companies that are heavily reliant on e-commerce systems and wireless networks are extremely vulnerable to the theft and loss of critical information in transmission. Policies and procedures should be documented and carried out to ensure that all transmitted data is protected. The auditor should verify that management has controls in place over the data encryption management process. Access to keys should require dual control, keys should be composed of two separate components and should be maintained on a computer that is not accessible to programmers or outside users. Furthermore, management should attest that encryption policies ensure data protection at the desired level and verify that the cost of encrypting the data does not exceed the value of the information itself. All data that is required to be maintained for an extensive amount of time should be encrypted and transported to a remote location. Procedures should be in place to guarantee that all encrypted sensitive information arrives at its location and is stored properly. Finally the auditor should attain verification from management that the encryption system is strong, not attackable and compliant with all local and international laws and regulations.

A network diagram can assist the auditor therapist in this process. The next question an auditor should ask is what critical information this network must protect. Things such as enterprise systems, mail servers, web servers, and host applications accessed by customers are typically areas of focus. It is also important to know who has access and to what parts. Do customers and vendors have access to systems on the network?

Can employees access information from home? Lastly the auditor should assess how the network is connected to external networks and how it is protected. Most networks are at least connected to the internet, which could be a point of vulnerability. These are critical questions in protecting networks. Encryption and it audit edit In assessing the need for a client to implement encryption policies for their organization, the auditor should conduct an analysis of the clients risk and data value. Companies with multiple external users, e-commerce applications, and sensitive customer/employee information should maintain rigid encryption policies aimed at encrypting the correct data at the appropriate stage in the data collection process. Auditors should continually evaluate their clients encryption policies and procedures.

Availability: Networks have become wide-spanning, crossing hundreds or thousands of miles which many rely on to access company information, and lost connectivity could cause business interruption. Access/entry point: Networks are vulnerable to unwanted access. A weak point in the network can make that information available to intruders. It can also provide an entry point for viruses and Trojan horses. Controls edit Interception controls: Interception can be partially deterred by physical access controls at data centers and offices, including where communication links terminate and where the network wiring and distributions are located.

Encryption also helps to secure wireless networks. Availability controls: The best control for this is to have excellent network architecture and monitoring. The network should have redundant paths between every resource and an access point and automatic routing to switch the traffic to the available path without loss of data or time. Access/entry point controls: Most network controls are put at the point where the network connects with external network. These controls limit the traffic that pass through the network. These can include firewalls, intrusion detection systems, and antivirus software. The auditor should ask certain questions to better understand the network and its vulnerabilities. The auditor should first assess what the extent of the network is and how it is structured.

Additionally, environmental controls should be in place to ensure the security of data center equipment. These include: Air conditioning units, raised floors, humidifiers and uninterruptible power supply. Backup procedures The auditor should verify that biography the client has backup procedures in place in the case of system failure. Clients may maintain a backup data center at a separate location that allows them to instantaneously continue operations in the instance of system failure. Issuing the review write report edit The data center review report should summarize the auditors findings and be similar in format to a standard review report. The review report should be dated as of the completion of the auditor's inquiry and procedures. It should state what the review entailed and explain that a review provides only "limited assurance" to third parties. The audited systems edit network vulnerabilities edit main article: Computer security audit Interception: Data that is being transmitted over the network is vulnerable to being intercepted by an unintended third party who could put the data to harmful use.

Equipment The auditor should verify that all data center equipment report is working properly and effectively. Equipment utilization reports, equipment inspection for damage and functionality, system downtime records and equipment performance measurements all help the auditor determine the state of data center equipment. Additionally, the auditor should interview employees to determine if preventative maintenance policies are in place and performed. Policies and Procedures All data center policies and procedures should be documented and located at the data center. Important documented procedures include: data center personnel job responsibilities, back up policies, security policies, employee termination policies, system operating procedures and an overview of operating systems. Physical security / environmental controls The auditor should assess the security of the clients data center. Physical security includes bodyguards, locked cages, man traps, single entrances, bolted down equipment, and computer monitoring systems.

access to the data center. Adequate environmental controls are in place to ensure equipment is protected from fire and flooding. Performing the review edit The next step is collecting evidence to satisfy data center audit objectives. This involves traveling to the data center location and observing processes and within the data center. The following review procedures should be conducted to satisfy the pre-determined audit objectives: Data center personnel All data center personnel should be authorized to access the data center (key cards, login IDs, secure passwords, etc.). Data center employees are adequately educated about data center equipment and properly perform their jobs. Vendor service personnel are supervised when doing work on data center equipment. The auditor should observe and interview data center employees to satisfy their objectives.

To adequately determine whether or not the clients goal is being achieved, the auditor should perform the following before conducting the review: meet with it management to determine possible areas of concern. Review the current it organization chart, review job descriptions of data center employees. Research all operating systems, software applications and data center equipment operating within the data center. Review the companys it policies and procedures. Evaluate the companys it budget and systems planning documentation. Review the data centers disaster recovery plan, establishing audit objectives edit, the next step in conducting a review of a corporate data center takes place when the auditor outlines the data center audit objectives. Auditors consider multiple factors that relate to data center procedures and activities that potentially identify audit risks in the operating environment and assess the controls in place that mitigate those risks. After thorough testing and analysis, the auditor is able to adequately determine if the data center maintains first proper controls and is operating efficiently and effectively. Following is a list of objectives the auditor should review: Personnel procedures and responsibilities including systems and cross-functional training.
