...Assessment Introduction In the war zone that is the modern Internet, manually reviewing each networked system for security flaws is no longer feasible. Operating systems, applications, and network protocols have grown so complex over the last decade that it takes a dedicated security administrator to keep even a relatively small network shielded from attack. Each technical advance brings wave after wave of security holes. A new protocol might result in dozens of actual implementations, each of which could contain exploitable programming errors. Logic errors, vendor-installed backdoors, and default configurations plague everything from modern operating systems to the simplest print server.Yesterday’s viruses seem positively tame compared to the highly optimized Internet worms that continuously assault every system attached to the global Internet. To combat these attacks, a network administrator needs the appropriate tools and knowledge to identify vulnerable systems and resolve their security problems before they can be exploited. One of the most powerful tools available today is the vulnerability assessment, and this chapter describes what it is, what it can provide you, and why you should be performing them as often as possible. Following this is an analysis of the different types of solutions available, the advantages of each, and the actual steps used by most tools during the assessment process.The next section describes two distinct approaches used by the...

...Enterprise network across the world are always looking for the easiest ways to manage their networks with a more automated process that can assist network administrators with troubleshooting and maintaining these networks. As a whole network management tools are a huge benefit to these networks and consist of five essential categories that are a must have across the board. The standard is called FCAPS which stands for: Fault, Configuration, Accounting, Performance, and Security. Fault management is one of the most essential parts of a network management tool. The purpose of the Fault Management tool is to find and repair any faults that occur within a network. It has the ability to alert to critical alerts and monitor various servers within the network. This management tool continuously checks CCM servers, unity/exchange servers as well as ensuring that they are backed up completely. Fault management also provides an overview or topology of the network to show what is running smoothly and where active faults are occurring. Configuration is essentially the way that the management software and devices are setup. Configuration will ensure that the network administrators get the alerts they want to see, setup auto fault alerts and ensuring that they can be automatically repaired if possible. Configuration is an essential part of a network management tool and allows customization for network administrators to operate the tools the way they need to for the company needs...

...The Tools of Network Security Name Date Class Professor School Introduction Network security can be hard in the environment of constantly changing technology. Strong protection does not have one simple solution. Anyone who is concerned with the protection of their computer, data, or network needs to be ready to spend time researching their specific needs to protect all the different layers and domains that can be attacked. The areas that need the most attention are port scanning, protocol analysis, vulnerability tests, intrusion prevention, firewall use, VPN security, internet filtering, and password recovery. Users need to become proactive when it comes to their network’s security by knowing what tools are the best for the job and being able to implement these tools quickly and correctly. Port Scanning Port scanning and IP scanning is an important step towards network security. A port scanner checks for available virtual ports on your network and can identify if they are open or closed. Finding out which ports are open allows network administrators to take appropriate protective actions by closing or blocking traffic to and from those open (Network Security Tools, 2013). Nmap is the major tool of choice for most network administrators. It is an affordable choice because it is a free open source tool. Nmap supports most operating systems and comes in wither a traditional command line interface or GUI version (Nmap, 2013). Nmap works by using raw IP packets...

...activities, such as port scans and ping sweeps, which can lead to intrusion of systems of a company or network, which enables the intruders to gain access to the systems and do changes in the settings or extract important information. These activities can be detected and stopped or prevented using special skills tool set. INTRODUCTION One of the most common disreputable computer activities are ping sweeps and port scans. They lead to breach of systems by intruders which can harm the whole system or network protocols. There are millions of entities around the world that utilize the internet and the problem is that, many are unaware of the threats and vulnerabilities that are lurking around. These probes can be detected and prevented for to be in a safe position rather than compromise. Ping Sweep and Port Scans Events Two methods that are used to attack a network is ping sweep and port scans. These activities can be used with malicious intent against, as well as, in effort to try to protect a network. Ping sweeps and port scans has been a notorious and yet a useful tool for hackers and system administrators. Ping sweeps and port scans at times can be a bother to both system administrators and network managers. Ping sweeps and port scans work together and can be dangerous but it also can be prevented. A ping sweep, also known as an internet control message protocol sweep (ICMP) is a basic network scanning technique used to determine the range of Internet Protocol (IP) addresses...

...Basic Components of Network Management Systems Matthew D. Miller DeVry University A network management system is a system that is made up of hardware and software, whose job it is to manage the communications, software, and computer hardware of a network (Hill Associates, 2008). There are many different tools and components that help to make up a network management system. Some of these tools include trouble ticket systems, help desk systems, alarm correlation, maintenance tools, etc (Hill Associates, 2008). Along with all these tools there are four basic components that a network management system consists of. They are the agent, network management station, network management protocol, and the management information (Hill Associates, 2008). As mentioned before a network management system has many tools available to use. Trouble ticket systems are used to manage and keep track of any and all issues relating to the network (OTRS Team, 2012). A very useful feature of trouble ticket systems is that they save and archive the tickets with all pertinent information like who was involved, the problem and any notes or solutions (OTRS Team, 2012). In case a particular event occurs again the help desk team has a reference to look to for assistance. With any kind of machine or system, maintenance must take place in order for it to perform to its full potential. Software and hardware updates are essential for the smooth running of a network (TWD & Associates, Inc., 2012)...

...Seymour Security Authentication Process Like most people who are computer users, you do not simply turn on your computer and start accessing programs. There are systems put in place by the user, or the administrator of the network to ensure that the properly authorized people gain access to their information. Specific profiles are created to differentiate amongst the users that allow each unique user to create, delete, and print or any other process they have access to. The process needs to be thoroughly planned out, and there also has to be a determination how whether it will be managed locally, or by third party software. This management of access controls actually comes in four different steps. The steps are: Identification, Authentication, Authorization, and finally, Accountability. No administrator worth his salt will incorporate any sort of security authentication process without these four basic steps. A properly configure authentication process will protect your network from such threats as password cracking tools, brute force attacks, the abuse of system rights and outright impersonation of authenticated users. Identification is the first of the four steps of the security process. Anyone that wishes to gain access to a system is referred to as a supplicant, and the tool that they use to gain entry to the system is referred to as an Identifier. This identifier can be a myriad of different references to uniquely identify the supplicant. The identifier should be able to...

...Fort SEC 280 Professor Dau July 15, 2012 Ping Sweeps and Port Scans With computer networks becoming larger hackers are looking more and more for ways to illegally gain access to our networks and procure information about our customers that they can use for their gain. Some tools that hackers are using are called ping sweeps and port scans. Now in the hands of Network Administrators these tools are not something to be afraid of, but in the hands of hackers they are something to be aware of because they have the ability to provide relevant information to a potential attacker. Ping sweeps and port scans will probably be the first steps of the attack because they provide the potential attacker a lot about our network as well as services, and open ports, on a computer system or our network. Ping sweep would be the first tool an attacker would take when he chooses to target our company’s computer systems. It is made up of a series of ICMP echo requests sent to a range of IP addresses to determine which IPs are in use by a host. A ping sweep is a valuable tool that can provide an attacker with a network map of all devices on the network, including hosts, routers, and other networked devices. With this information an attacker can establish an attack plan on network servers and hosts or can be used just to clog up the network. With the appropriate firewall in place protecting the network from pings outside of the LAN, then we can eliminate these types of ping sweeps. However...

...network Network topology—This is usually done in the form of a diagram that shows the major network nodes, such as routers, switches, firewalls, and servers, and how they are all interconnected. Normally, printers and workstations are not included. Server information—This is all of the information on servers that you will need to manage or administer them, such as name, functions, IP address, disk configuration, OS and service pack, date and place of purchase, warranty, and so forth. Router and switch port assignments—This includes detailed information on WAN configuration, VLANs, or even the assignment of a port to a network node via the patch panel. Configuration of network services—Network services, such as DNS, WINS, DHCP, and RAS, are critical to the operation of the network. You should describe in detail how they are structured. Although it would be possible to derive that information by inspecting the servers, the point is to save that time by having it documented in an easy-to-decipher format. Domain policies and profiles—You can restrict the capabilities of network users with the Policy Editor in Windows NT or with Group Policies in Windows 2000. You can also create roaming profiles that are stored on a server rather than on local machines. This kind of configuration, if used, should be documented. Mission-critical applications—You must document how these are maintained, as well as what typically goes wrong with them and how you resolve problems...

...carefully planned in order to meet all of the needs of a companies complicated network design. The design objectives depend on what problems are anticipated, what services to allow or deny, and what level of risk is acceptable. How to cover these objectives is a lot to consider; how much money is available or allowed in order to implement this design, how long does the administrator have to complete this design, and is the expertise level of knowledge available in order to correctly implement this design? The most daunting task of all; which firewall to implement? A firewall comes in all shapes, sizes, and specification. All are meant to make a network more secure, but where to start? Is it a software driven firewall or hardware bases firewall used? Which type of firewall; database, network based, host bases, or application bases? What are the differences between them, how they work or what they actually do? Will it do more harm than good? It can all be very confusing when trying to protect a network and figure out which firewall is best fit. All of these are very important questions that should be answered before starting the installation and implementation of a firewall. Hopefully the answer to these questions will become clear as firewalls are discussed further in this paper. Firewalls What is a firewall and how does it work? By definition a firewall protects an internal network from malicious access from the outside. A firewall basically comes in two different...
