The various security controls in the SDLC design phase are as follows:

Misuse Case Modeling: It is important that the inverse of the misuse cases be modeled to understand and address the security aspects of the software. The requirements traceability matrix can be used to track the misuse cases to the functionality of the software. Security Design and Architecture Review: This control can be introduced when the teams are engaged in the "functional" design and architecture review of the software. Threat and Risk Modeling: Threat modeling determines the attack surface of the software by examining its functionality for trust boundaries, data flow, entry points, and exit points. Risk modeling is performed by ranking the threats as they pertain to the users organization's business objectives, compliance and regulatory requirements and security exposures. Security Requirements and Test Cases Generation: All the above three security controls, i.e., Misuse Case Modeling, Security Design and Architecture Review, and Threat and Risk Modeling are used to produce the security requirements.

Snort is an open source network intrusion prevention and detection system that operates as a network sniffer. It logs activities of the network that is matched with the predefined signatures. Signatures can be designed for a wide range of traffic, including Internet Protocol (IP), Transmission Control Protocol (TCP), User Datagram Protocol (UDP), and Internet Control Message Protocol (ICMP). The three main modes in which Snort can be configured are as follows:

Sniffer mode: It reads the packets of the network and displays them in a continuous stream on the console. Packet logger mode: It logs the packets to the disk. Network intrusion detection mode: It is the most complex and configurable configuration, allowing Snort to analyze network traffic for matches against a user-defined rule set. Answer: B is incorrect. Macof is a tool of the dsniff tool set and used to flood the local network with random MAC addresses. It causes some switches to fail open in repeating mode, and facilitates sniffing. Answer: C is incorrect. Sourcefire is the company that owns and maintains Snort. Answer: A is incorrect. NETSH is not a network intrusion detection system. NETSH is a command line tool to configure TCP/IP settings such as the IP address, Subnet Mask, Default Gateway, DNS, WINS addresses, etc.

Exception handling is a computer hardware mechanism or programming language construct that handles the occurrence of events. These events occur during the software execution process and interrupt the instruction flow. Exception handling performs the specific activities for managing the exceptional events.

CSRF (Cross-Site Request Forgery) is a malicious exploit of a website, whereby unauthorized commands are transmitted from a user trusted by the website. It is also known as a one-click attack or session riding. CSRF occurs when a user is tricked by an attacker into activating a request in order to perform some unauthorized action. It increases data loss and malicious code execution. Answer: A is incorrect. Cross-site scripting (XSS) is a type of computer security vulnerability typically found in web applications which enable malicious attackers to inject client-side script into web pages viewed by other users. An exploited cross-site scripting vulnerability can be used by attackers to bypass access controls, such as the same origin policy. Cross-site scripting carried out on websites were roughly 80% of all security vulnerabilities documented by Symantec as of 2007. Their impact may range from a petty nuisance to a significant security risk, depending on the sensitivity of the data handled by the vulnerable site, and the nature of any security mitigations implemented by the site owner. Answer: C is incorrect. A side channel attack is based on information gained from the physical implementation of a cryptosystem, rather than brute force or theoretical weaknesses in the algorithms (compare cryptanalysis). For example, timing information, power consumption, electromagnetic leaks or even sound can provide an extra source of information which can be exploited to break the system. Many side- channel attacks require considerable technical knowledge of the internal operation of the system on which the cryptography is implemented. Answer: B is incorrect. Injection flaws are the vulnerabilities where a foreign agent illegally uses a sub-system. They are the vulnerability holes that can be used to attack a database of Web applications. It is the most common technique of attacking a database. Injection occurs when user-supplied data is sent to an interpreter as part of a command or query. The attacker's hostile data tricks the interpreter into executing involuntary commands or changing data. Injection flaws include XSS (HTML Injection) and SQL Injection.

Security constraint is a type of declarative security, which specifies the protection of web content. It also specifies access privileges to a collection of resources by using the URL mapping. A deployment descriptor is used to define the security constraint. Security constraint includes the following elements: Web resource collection Authorization constraint User data constraint Answer: A is incorrect. Code Access Security (CAS), in the Microsoft .NET framework, is Microsoft's solution to prevent untrusted code from performing privileged actions. When the CLR (common language runtime) loads an assembly it will obtain evidence for the assembly and use this to identify the code group that the assembly belongs to. A code group contains a permission set (one or more permissions). Code that performs a privileged action will perform a code access demand, which will cause the CLR to walk up the call stack and examine the permission set granted to the assembly of each method in the call stack. The code groups and permission sets are determined by the administrator of the machine who defines the security policy. Answer: D is incorrect. Access Management is used to grant authorized users the right to use a service, while preventing access to non- authorized users. The Access Management process essentially executes policies defined in IT Security Management. It is sometimes also referred to as Rights Management or Identity Management. It is part of Service Operation and the owner of Access Management is the Access Manager. Access Management is added as a new process to ITIL V3. The sub-processes of Access Management are as follows: Maintain Catalogue of User Roles and Access Profiles Manage User Access Requests Answer: C is incorrect. Configuration Management (CM) is an Information Technology Infrastructure Library (ITIL) IT Service Management (ITSM) process. It tracks all of the individual Configuration Items (CI) in an IT system, which may be as simple as a single server, or as complex as the entire IT department. In large organizations a configuration manager may be appointed to oversee and manage the CM process.

Anonymous authentication is an authentication method used for Internet communication. It provides limited access to specific public folders and directory information or public areas of a Web site. It is supported by all clients and is used to access unsecured content in public folders. An administrator must create a user account in IIS to enable the user to connect anonymously. Answer: D is incorrect. Multi-factor authentication involves a combination of multiple methods of authentication. For example, an authentication method that uses smart cards as well as usernames and passwords can be referred to as multi-factor authentication. Answer: C is incorrect. Mutual authentication is a process in which a client process and server are required to prove their identities to each other before performing any application function. The client and server identities can be verified through a trusted third party and use shared secrets as in the case of Kerberos v5. The MS-CHAP v2 and EAP-TLS authentication methods support mutual authentication.

Answer: B is incorrect. Biometrics authentication uses physical characteristics, such as fingerprints, scars, retinal patterns, and other forms of biophysical qualities to identify a user.

Risk assessment includes identification of vulnerabilities, assessment of losses caused by threats materialized, cost-benefit examination of countermeasures, and assessment of attacks. Answer: A is incorrect. This process is included in the vulnerability management.

DITSCAP stands for DoD Information Technology Security Certification and Accreditation Process. The DoD Directive 5200.40 (DoD Information Technology Security Certification and Accreditation Process) established the DITSCAP as the standard C&A process for the Department of Defense. The Department of Defense Information Assurance Certification and Accreditation Process (DIACAP) is a process defined by the United States Department of Defense (DoD) for managing risk. DIACAP replaced the former process, known as DITSCAP, in 2006. Answer: B is incorrect. This DoD Directive is known as National Industrial Security Program Operating Manual. Answer: C is incorrect. This DoD Directive is known as Defense Information Management (IM) Program. Answer: A is incorrect. This DoD Directive is known as Management and Control of Information Requirements.
