Analysis Of The Position Of An Information Security Officer

Also one has to know what type of network has been worked on, what network topologies the security is going on. The ring topology is going to be different from a bus or star topology. The hybrid is going to be different from the mesh topology or even wireless, this can be one of the hardest networks to protect. Also one has to think about size when it comes to building a network. Most people most of the time can’t tell the different between a big network and a small network. Big networks mostly consist of multiple several servers, computers and other device which connects to the network from the outside. All these devices need to be protected or secured when it’s connected to the internet and the network. Big networks are used mostly in bigger institution and organization where by 30 or more computers and server are used and are all linked to the network. Also speed is a factor when it comes to the internet networks but most importantly it’s important to bigger institutions and companies. Policy is one thing that most organization needs because if they want their network and the use of internet to be secured. Policies have to cover all aspect that the network is in. There has to be a lot of thought put in and all devices and how they connect to the outside world has to be considered. Small networks sometimes don’t have benefits and the down fall bigger networks have. Although speed is a factor, one

It is important to recognize irregularities which appear in the Network & Network devices. And I will be

For the purpose of this assignment snort will be used as intrusion detections systems which is an open source IDS, snort has the ability to monitor traffics in real time and packet locking its also inspecting each packets as they enters into the network, Snort can be used as packet sniffer to analyse the network traffic in order to detect any bizarre looking packets or payloads which might have malicious data in it. Snort can also detect payloads attacks against the network or host system including but not limited to stealth port scan, and buffer overflows.

Firewalls are set up on computers to help protect computers and other devices from attacks from potentially harmful websites and other resources. Proxies are servers that act as a middle man for computers. They allow users to make indirect connections to other servers. The LAN-to-WAN domain is where the infrastructure connects to the Internet. Updates, firewalls and proxies will help to keep things running and help to keep it protected.

This is a security system that was executed in software or hardware that is used to prevent unauthorised access to or from an intranet which is a private network, firewalls are frequently used during that time. They work by filtering packets of data as they enter or leave the network, on the other hand they apply security to some particular applications, firewalls are like the front line for defence, they make sure that everything is secure before they allow anyone to enter or leave the network, which can help keep not only the computers but also the organisations and information safe.

The network team is doing its part to recommend updates to the network intrusion detection system. Also the team has setup alerts which will send email to the team when there is a change in the baseline network bandwidth which can be a precursor to an attack. Additional monitoring has been enabled to alert the team when there is administrative access to the firewall. Also the team will work to build resiliency in the network to automatically switch the network to additional circuits when under this type of

Network-Based Scanner helps detect critical vulnerabilities for example mis-configured firewalls, risks associated with vendor-supplied software, vulnerable web servers, and risks associated with systems administration and network.

Assume I am the Information Technology manager of Hong Kong Disneyland, and I am responsible to manage and design the computer network as well as internet services. Due to limited time, budget and resources, and i will proposed four internet services to enable efficient communication with customers and internal staff. And I would like to suggest the security measures to ensure secure communication.

Assess the adequacy and effectiveness of the organization’s IS security policy. In addition, assess whether the control requirements specified in the organization’s IS security standards adequately protect the information assets of the organization. At a minimum, the standards should specify the following controls and require them to be applicable to all information systems:

Firewalls monitor network traffic in real time and either allows or denies certain traffic into or out of the network based on the type of firewall and the rules they are programmed to follow. Firewalls are a very important baseline in system infrastructure and design.

Despite its impact ping sweeps and port scans are best understood as a huge security threat on today's company's network system.

3. Most incident response do not have enough protection method. The main purpose of such incident response policy is reducing the attack damage and recovering the system. However, for some critical system such as programming database, financial support system, even a small damage may cause huge loss. For such systems, a better protection ability for incident response policy are extremely

Several procedures can be included in this policy including the importance of responding immediately to any intrusions that are detected, utilizing secure encryption for any internal or external messages, instituting regular audits to make sure security precautions are followed, implementing all vendor supplied security update patches, logging activity to detect any unusual events, and following news and computer information reports about new threats being circulated (Haring,

This is the step where the team determine if an incident has occurred. Based on events observation, indicators, the team look for deviations from normal operations. The team look for malicious acts or attempts to do harm. The security mechanism in place will help the team doing the identification. Incident handler team will use their experience to look at the signs and indicators. The observation could occur at network level, host level or system level. It’s where the team leverage the alerts and logs from routers, firewalls, IDS, SIEM, AV gateways, operating system, network flows, etc. After identifying an incident the team need to assess the impact. Notify the appropriate individuals or external parties. If there are reasons to believe
