Information security involves protecting computer systems and data from unauthorized access, cyber threats, and damage. It is a core part of the computer knowledge section in various banking and government exams. Practicing these concepts helps in understanding digital signatures, network security, and access control effectively.

Information Security Questions
A
Correct answer
Explanation
Footprinting is indeed the reconnaissance phase where attackers gather information about a target system before attempting intrusion. This includes collecting public information, DNS records, network topology, employee details, and other intelligence. It's a critical first step in both ethical hacking and malicious attacks, forming the basis for later exploitation phases.
-
An error will occur
-
Data passed between the client and the server is encrypted.
-
User IDs and passwords are passed to the server unencrypted
-
User IDs and passwords are encrypted before they are passed to the server.
A
Correct answer
Explanation
When a client requests SERVER_ENCRYPT authentication, the server must support password encryption. If the server is configured with SERVER authentication, it only accepts unencrypted credentials. Attempting this connection results in a security negotiation mismatch error.
-
Cryptography
-
Wrapping
-
Sandbox
-
Coding and Decoding
C
Correct answer
Explanation
The Android sandbox is a security mechanism that isolates applications from each other and from the system. Each app runs in its own sandbox with restricted permissions, preventing malicious or buggy apps from disrupting other applications or the OS. Cryptography is for encryption, wrapping is a programming concept, and coding/decoding are not security isolation mechanisms.
-
AES
-
Triple DES
-
Both
-
Option 2 only
C
Correct answer
Explanation
The correct answer is C (Both) because BlackBerry Enterprise Server uses both AES and Triple DES encryption to provide security. AES (Advanced Encryption Standard) is the newer, stronger standard, while Triple DES is an older algorithm still supported for backward compatibility. Options A and B are individually incomplete. Option D is wrong because it incorrectly excludes AES.
-
XML threat Protection in DP
-
Web application firewall in DP
-
Virus Protection
-
Denial of Service (DoS)
A
Correct answer
Explanation
SQL injection protection is provided by XML Firewall protection parameters in DataPower. While unintuitive, the XML Firewall's threat protection capabilities include SQL injection detection alongside other injection attacks. Option B (Web Application Firewall) provides broader HTTP-level protection but XML threat protection specifically handles SQL injection in the XML context.
-
handled at the machine level
-
handled at the Page level
-
handled at the domain level
-
handled at the sharepoint level
A,C,D
Correct answer
Explanation
SharePoint security is managed at multiple levels: domain level (Active Directory integration for authentication), machine level (server-level permissions), and SharePoint level (site, list, and item-level permissions). Page level security is not a distinct security tier in SharePoint - pages inherit permissions from the site/library. This is an MC-2 question requiring multiple selections.
-
Anonymous
-
Integrated Windows Authentication
-
Basic Authentication
-
Digest Authentication
-
Passport Authentication
-
PEAP
A,B,C,D,E
Correct answer
Explanation
IIS supports Anonymous (no authentication), Integrated Windows Authentication (Kerberos/NTLM), Basic Authentication (base64 encoded), Digest Authentication (hash-based), and Passport Authentication (Microsoft's centralized auth). PEAP is a wireless authentication protocol not part of IIS.
-
Security testing
-
Interface testing
-
Smoke testing
-
Sanity testing
A
Correct answer
Explanation
Security testing is the correct answer because it explicitly validates authentication mechanisms, session management, cookie handling, and access controls. Cookie and session management are critical security features that must be tested for vulnerabilities like session hijacking, cookie tampering, and unauthorized access.
-
Use the epw parameter in FTP component
-
.netrc file
-
settting AB_FTP_PASSWORD configuration variable
-
All of the above
D
Correct answer
Explanation
Ab Initio provides multiple methods to encrypt FTP component passwords: the epw parameter in the FTP component itself, using a .netrc file for stored credentials, or setting the AB_FTP_PASSWORD configuration variable. All three approaches are valid and serve different security and operational needs.
-
Information hiding
-
Minimizing interdependencies among modules
-
Make implementation independent
-
All of these options
A
Correct answer
Explanation
Encapsulation achieves information hiding by bundling data and methods within a class and controlling access through public interfaces. The other options are benefits of information hiding, not encapsulation itself. Encapsulation is the mechanism that enables information hiding, which in turn reduces interdependencies and supports implementation independence.
-
Minimum password length
-
Maximum inactivity time limit
-
Alphanumeric password requirement
-
Prompt user to set new password
A,B,C,D
Correct answer
Explanation
Android's Device Administration API supports policies including minimum password length, maximum inactivity timeout (after which the device locks), password quality requirements like alphanumeric content, and requesting/prompting the user to reset or set a new password. Thus, all listed policies are correct.
-
The attribute that uniquely identifies the person
-
The attribute that contains the full name of the person
-
The attribute that is used by IBM Tivoli Identity Manager to resolve account ownerships during reconciliations
-
The attribute that contains the fully qualified DN of the person in the IBM Tivoli Identity Manager ou=person container
A
Correct answer
Explanation
In IBM Tivoli Identity Manager (TIM) CSV feed configuration, the name attribute maps to the attribute that uniquely identifies each individual person record in the source CSV file during reconciliation.
-
None; password rules cannot be extended.
-
Password rules can be extended using JavaScript.
-
Password Java APIs can be used to extend password rules.
-
Password rules can be extended using the Pluggable Authentication Module (PAM) framework.
C
Correct answer
Explanation
IBM Tivoli Identity Manager provides Password Java APIs that allow developers to extend standard password rules with custom logic. This enables organizations to implement password policies beyond the built-in rules. JavaScript and PAM are not the extension mechanisms for TIM password rules.
-
Only reconcile once per week.
-
Disable policy evaluation during all reconciliations.
-
Exclude any attributes in the reconciliation that are not related to policy evaluation.
-
Increase the size of the memory in the WebSphere JVM (Java Virtual Machine) until the reconciliation meets performance requirements.
C
Correct answer
Explanation
Excluding attributes unrelated to policy evaluation reduces data transfer and processing overhead, improving reconciliation performance. Weekly reconciliation frequency is unrelated to performance optimization. Disabling policy evaluation would compromise functionality, and JVM tuning should follow proper sizing rather than arbitrary increases.
-
Enable IBM Tivoli Identity Manager server-side sorting.
-
Limit the number of attributes returned by the adapter and processed by IBM Tivoli Identity Manager.
-
Decrease the default maximum duration as specified in the reconciliation schedule.
-
Decrease the SearchALUnusedTimeout configuration parameter in the RMI Dispatcher.
B
Correct answer
Explanation
Limiting attributes returned by the adapter reduces processing overhead and improves performance. Server-side sorting is not a performance lever for reconciliation. Decreasing duration might cause incomplete reconciliations. SearchALUnusedTimeout is unrelated to this performance issue.
