Information Security Policy Essay1. Executive SummaryDue in Week Nine Write 3 to 4 paragraphs giving a bottom-line summary of the specific measureable goals and objectives of the security measure plan, which can be implement to define optimal security architecture for the selected occupancy scenario.The goal of this security polity is to lay out a basic plan for a secure info organization to be employ by Bloom Design gathering. This form _or_ scheme of government exit protect the orders transcriptions from threats that can come from humans and from natural disasters as well. The policy ordain also put into consideration the privacy, reputation, rational property and productivity of the Bloom Design gathering. The continued operation of this company depends on beingness able to plan of attack and use resources within the organization and being able to remote entree with security. Each persons role in the company ordain be considered and appropriate admissio n fee will be given to warrant the efficient operation of the affair, while non giving approach shot to those who are not authorized. This policy will also help in the companys adherence to any governmental regulations. Any disruptions of service or security related issues will be dealt with immediately by means of administration software that is automated to handle certain threats. More serious issues will be dealt with by the IT staff whose responsibility it is to oversee the everyday operation of the information system.2. groundworkDue in Week One Give an overview of the company and the security goals to be achieved.2.1. Company overviewThe Bloom Design Group is a company that offers interior(a) design services to businesses and individuals around the world. There corporate status is located in New York with a secondary office in Los Angeles for handling trading operations on the West coast. They have a web site that offers their customers the ability to work up their d esigns online and then purchase them through a electronic revisal processing system. Also, the designers use secure logarithmins and passwords to access the web site. A cock-a-hoop number of the workforce work remotely possibly using tablets or ipads connected to secure VPNs or Virtual Private mesh topologys.2.2. Security policy overviewBloom Design sort already provides secure logins and cyberspaces to their employees so they already have approximately symbol of system setup already. However, this does not mean it is a system that works efficiently. I think the appropriate security policy to implement for this project would be system specific.2.3. Security policy goalsAs applies to your selected scenario, explain how the confidentiality, integrity, and availability principles of information security will be addressed by the information security policy.2.3.1. ConfidentialityThe policy I plan to implement will help to protect information by reviewing how the company stores huffy information such as employee and node records, trade secrets, and some other sensitive data.2.3.2. IntegritySince the company will be using passwords and secure logins the system will not be accessible to the public. So the primary focus should be on the employees. Authentication and verification can be done using a data log to keep records of employees activeness while on the companys VPN. Also, the use of a firewall will help with integrity as it will pr stillt employees from unknowingly accessing damaging websites.2.3.3. handinessThe policy I plan to use will help with back-up and recovery by the possible use of cloud fund or a primal data storage center. Although they are already using secure logins for access control the whole system needs to be reviewed. This is to make sure except authorized personnel have access to sensitive areas.3. misfortune Recovery PlanDue in Week Three For your selected scenario, describe the key elements of the accident Recovery Plan to be used in case of a disaster and the plan for raveling the DRP.3.1. Risk Assessment3.1.1. Critical business processesThe mission-critical business systems and services that must be protected by this DRP are Payroll, Human Resource Data, POS backup media, and Web Servers and their services.3.1.2. Internal, external, and environsal risksExamples of internal risks that may affect business are unauthorized accessby individuals who are employed by the company, and those who arent employed by the company but still have access to individual stores computer systems, applications, or areas where the servers and backup media are located. Other external and environmental risks involve fire, floods, power outages, hardware failure, software glitches and failure, storms, and other acts of nature.3.2. Disaster Recovery StrategyMost cases, having an alternative site (a igneous site, or cold site depending on the disaster) would be the correct way of dealing with roughly disasters. With Blo om design group I think having a warm site facility would be the best option. Warm sites are cheaper than hot sites but require more effort. On the other hand, they are more expensive than cold-site facilities but less labor intensive and more likely to be stiff in a disaster. Also, having a backup and retention site to work from, and recover from for the main servers and web services is a good idea.3.3. Disaster Recovery Test PlanFor each testing method listed, briefly describe each method and your rationale for why it will or will not be included in your DRP test plan.3.3.1. Walk-throughsThis test plan would be a great way for the key personnel to come together and formulate a plan of action in the event of an emergency. Due to Bloom Design group being spread across a big(a) area it might require some video conferencing and traveling on the part of some employees.3.3.2. SimulationsI think this test plan is the most effective when compared to the others. Simulating an actual eme rgency is a great way for good deal to get used to operating in a critical time under pressure. This will show you where your people have their strengths and weaknesses when trying to recover from a disaster.3.3.3. ChecklistsThis passive guinea pig of testing would be a good system to implement on a weekly or monthly basis depending on the needs of the company. This will help in detecting problems before they become a major issue.3.3.4. Parallel testingSince Bloom Design group is updating their security parameters and do not have an equal type of system already implemented parallel testing would not be appropriate for this security policy.3.3.5. Full interruptionI think this is another very effective way to test the system in the event of an emergency. However, to minimize inconveniences to the customers it would have to be done during off hours.4. Physical Security PolicyDue in Week cardinal Outline the Physical Security Policy. Merkow and Breithaupt (2006) state, an often over looked connection between physical systems (computer hardware) and analytical systems (the software that runs on it) is that, in order to protect logical systems, the hardware running them must be physically secure (p.165). Describe the policies for securing the facilities and the policies of securing the information systems. Outline the controls needed for each category as relates to your selected scenario. These controls may include the followingPhysical controls (such as perimeter security controls, badges, keys and combination locks, cameras, barricades, fencing, security dogs, lighting, and separating the workplace into functional areas) Technical controls (such as smart cards, audit trails or access logs, intrusion detection, alarm systems, and biometrics) Environmental or life-safety controls (such as power, fire detection and suppression, heating, ventilation, and air conditioning)4.1. Security of the building facilities4.1.1. Physical entry controlsAt the two office locati ons (Los Angeles, New York) for Bloom Design Group I would use employee badges that double as an electronic key to access the building and other sensitive locations. This will work in conjunction withan access control system that limits entree/exit to the offices through one main entrance. There will be an employee entrance as well also to be accessed by an electronic badge.4.1.2. Security offices, ways and facilitiesFor the security offices I would implement biometric scanners due to the sensitive equipment inside. Other rooms and facilities of a sensitive nature will lend oneself electronic badges with a photo and name of the employee.4.1.3. Isolated delivery and loading areasFor these areas I would implement electronic key card access with the use of a CCTV system recording to a DVR. With a CCTV camera located on the driver door in the loading area the person responsible for deliveries will know when a delivery is being made and can observe he outside environment before opening the door.4.2. Security of the information systems4.2.1. Workplace protectionFor this part of the security policy I would utilize pre-employment screening and mandatory vacation time. This prevents people from hiding illegal activities while seting their duties. Also, I would setup privileged entity controls so operators and system administrators have special access to computing resources.4.2.2. Unused ports and cablingFor reinvigorated ports I would use a piece of security equipment that can be plugged into the unused port and can only be removed by someone with a special key. This will help prevent unauthorized access into the cyberspace. For unused cabling I would secure it in a secure storage room which can only be accessed by authorized personnel. If the above mentioned equipment isnt available then the port should be removed.4.2.3. Network/server equipment creation that this is some of the most critical equipment for business operations I would use biometric locks and scann ers on any room thatcontains this equipment. Also these rooms will be environmentally controlled with air conditioners and dehumidifiers to accommodate the equipment to operate at peak efficiency.4.2.4. Equipment maintenanceSince a lot of the equipment is spread across a large region I would utilize remote communication connections to troubleshoot issues. If the maintenance need is more severe than I would have a small centrally located facility that specializes in assessing and repairing go equipment.4.2.5. Security of laptops/roaming equipmentFor laptops and roaming equipment I would install all devices with a GPS tracker and encryption software to protect against unauthorized access. The equipment itself would be stored in a secure storage room with access being tightly controlled.5. Access Control PolicyDue in Week Seven Outline the Access Control Policy. Describe how access control methodologies work to secure information systems5.1. AuthenticationAuthentication credentials p ermit the system to verify ones identification credential. Authenticating yourself to a system tells it the information you have established to prove that you are who you say you are. Most often, this is a simple password that you set up when you receive the privilege to access a system. You may receive an poseed password initially with the requirement that you must reset it to something more personalsomething that only you can remember. However, passwords are the easiest type of authentication to beat. Free and widely available programs are available on the Internet to break the security afforded by passwords on most of the commonly used systems.With two or three factors to attest, an information owner can gain confidence that exploiters who access their systems are indeed authorized to access their systems. This is accomplished by adding more controls and/or devices to the password authentication process. Biometric scanning uses unique human characteristics to identify whether the person trying to gain access is authorized to enter or not. One commonapproach to managing IDs and passwords is to create a password or PIN vault. These programs use secure methods to locally store IDs and passwords that are protected by a master password that unlocks the vault when its needed.5.2. Access control strategy5.2.1. Discretionary access controlThe discretionary access control system will be used for Bloom Design Group because this is the favored approach in the corporate environment and due to the wide area of operations this will furnish several authorized users to have access to the system at any given time. The principle of least privilege is the predominant strategy to assure confidentiality. The objective is to give people the least amount of access to a system that is needed to perform the job theyre doing. The need-to-know dictates the privilege (authority) to perform a transaction or access a resource (system, data, and so forth). An information owner is one who maintains overall responsibility for the information within an information system. For the Bloom Design Group the information owner is going to be the corporate head of IT operations.5.2.2. Mandatory access controlIn a system that uses mandatory access control (MAC also called nondiscretionary access control), the system decides who gains access to information based on the concepts of subjects, objects, and labels, as defined below. Since the Bloom Design Group is spread out over such a large area I do not think this is the best choice for this scenario. MAC is mend suited for military or governmental systems.5.2.3. Role-based access controlRole-based access control (RBAC) groups users with a common access need. You can assign a role for a group of users who perform the same job functions and require similar access to resources. This would also be appropriate for this scenario because it will allow the information owner to easily assign access to certain groups such as designe rs, office personnel, customer service associates and so forth.5.3. away accessRemote Access Dial-In User Service (RADIUS) is a client/server protocol and software that enables remote access users to communicate with a centralserver to authenticate dial-in users and authorize their access to the requested system or service. RADIUS allows a company to set up a policy that can be utilise at a single administered mesh point. Having a central service also means that its easier to track usage for billing and for keeping network statistics. A virtual private network (VPN) is another common means for remote users to access corporate networks. With a VPN, a user connects to the Internet via his or her ISP and initiates a connection to the protected network (often using a RADIUS server), creating a private tunnel between the end points that prevents eavesdropping or data modification.6. Network Security PolicyDue in Week Nine Outline the Network Security Policy. As each link in the chain of network protocols can be attacked, describe the policies covering security services for network access and network security control devices.6.1. Data network overviewDue to the large geographic distances between Bloom Design Group offices a WAN is going to be utilized. WAN covers a larger geographic area than a LAN (technically, a network that covers an area larger than a single building). A WAN can span the entire nation or even the globe using satellites.6.2. Network security services6.2.1. AuthenticationAccess to documents can be restricted in one of two ways by asking for a username and password or by the hostname of the browser being used. For Bloom Design Group employees will need to enter a user ID and password to access restricted documents and sites.6.2.2. Access controlUnlike authentication, which is security-based on the users identity, restricting access based on something other than identity is called access control. For Bloom Design group access control to physical locations will be done by controlled by electronic badges. More sensitive areas such as the server rooms will utilize biometric scanners.6.2.3. Data confidentialityThis service protects data against unauthorized disclosure and has two components content confidentiality and message blend confidentiality. For Bloom Design group all messages transmitted and received through company offices will be encrypted to prevent the unauthorized viewing of sensitive company documents.6.2.4. Data integrityThe goal is to protect data from accidental or malicious modification whether during data transfer, data storage, or from an operation performed on it, and to continue it for its intended use. For Bloom Design Group the only people who will be authorized to make changes or modifications will be the Head of the IT subdivision and anyone else they deem necessary.6.2.5. NonrepudiationA service guaranteeing that the sender of a message cannot deny having sent the message and the receiver cannot d eny having received the message. I do not think this will be necessary for Bloom Design group. However, if it does then the proper modifications can always be made.6.2.6. Logging and monitoringThese services allow IS specialists to observe system activity during and after the fact by using monitoring and logging tools. These include operating system logs, server records, application log errors, warnings, and observation of network, switch and router traffic between network segments. I do not think this will be necessary for Bloom Design Group as a whole. However, it will be utilized for any programs having to do with the servers due to its sensitive business content.6.3. Firewall systemOutline the roles of the following network security control devices and how these basic security infrastructures are used to protect the companys network against malicious activity. Provide a description of each type of firewall system and how it is used to protect the network. Include how the firewal l system is or is not applicable to the companys network configuration in your selected scenario.6.3.1. Packet-filtering router firewall systemThe most common Internet firewall system consists of nothing more than a packet-filtering router deployed between the private network and the Internet. A packet-filtering router performs the typical routing functions of forwarding traffic between networks as well as using packet-filtering rules to permit or deny traffic.6.3.2. Screened host firewall systemThe second firewall example employs both a packet-filtering router and a bastion host. This firewall system provides higher levels of security than the previous example because it implements both Network-Layer security (packet-filtering) and Application-Layer security (proxy services). Also, an intruder has to penetrate two separate systems before the security of the private network can be compromised. This will be the option chosen for Bloom Design Group based on needs and cost. Since Bloom Design group is not a governmental or military related company then it doesnt require the most elaborate form of firewall protection.6.3.3. Screened-Subnet firewall systemThe nett firewall example employs two packet-filtering routers and a bastion host. This firewall system creates the most secure firewall system, as it supports both Network-Layer and Application-Layer security while defining a demilitarized zone (DMZ) network.7.
