4. CYBER SECURITY AWARENESS : DAY 2
• Vulnerabilities
• Network Security
• Access Control
• Physical Security
• Disaster Recovery

5. Vulnerability Assessments
Perform when:
• First deploy new/updated systems.
• New vulnerabilities have been identified.
• A security breach occurs.
• Need to document security state of systems.
Collect Store Organize Analyze Report

6. • Port scanner
• Protocol analyzer
• Packet analyzer
• Network enumerator
• Intelligence gathering
• Vulnerability scanner
Vulnerability Scanning

7. • Evaluate security by simulating an attack on a system.
• Verify a threat exists.
• Actively test and bypass security controls.
• Exploit system vulnerabilities.
• When compared to vulnerability assessment, it is:
• Less common.
• More intrusive.
• An objective measurement.
• A combination of multiple vulnerabilities to provide holistic understanding of vulnerability.
• Follow real attacker’s methodology, including target preparation/research stages.
• Difference between pen test and real attack is intent.
• Need explicit permission of target organization.
• Make sure organization knows test will not stop until attack is fully carried out.
• Report should include:
• Steps undertaken.
• Weaknesses identified.
• Recommendations.
Penetration Testing

8. Penetration Test Components
Component Description
Network scanning • Uses a port scanner to identify devices attached to target network and to
enumerate the applications hosted on the devices. This function is known as
fingerprinting.
Social engineering • Attempts to get information from users to gain access to a system.
• Tests for adequate user training.
• Stay mindful of ethical implications of deceiving people.
• Don't want to undermine your employees' trust in you or their coworkers.
War dialing • Uses a modem and software to dial a range of phone numbers to locate
computer systems, PBX devices, and HVAC systems.
War driving • Locates/attempts to penetrate wireless systems from public property, like a
sidewalk.
Vulnerability scanning • Exploits known weaknesses in operating systems and applications identified
through reconnaissance and enumeration.
Blind testing • Occurs when the target organization is not aware of penetration testing
activities.
Targeted testing • Target organization is informed of the test.
• Less disruption to organization due to a more controlled climate.

9. • Event logs contain detailed information.
• Often used to troubleshoot performance issues.
• Should also review as part of security control test process.
• Use an automated tool to help identify security events from mass of data.
• May need to configure network devices to capture desired level of detail in a log.
Event Log Review (Slide 1 of 2)

10. Common logged activities include:
• Authentication requests, both successful and unsuccessful.
• New user or group creation.
• Group membership changes.
• User privilege level changes.
• Resource access, such as opening, changing, and deleting files and folders.
• Client requests for server services.
• The number of transactions per hour of a particular service.
• Application or service shutdowns and restarts.
• System shutdowns and restarts.
• Service or system component errors and failures.
• System policy changes.
Event Log Review (Slide 2 of 2)

11. Wireless Security (Slide 1 of 2)
Wireless Security Protocol Description
WEP • Wired Equivalent Privacy.
• Relies on stream cipher with 24-bit initialization vector (IV).
• Attack on IV can easily predict short value.
• Can be compromised in minutes.
• Obsolete – do not use.
WPA • Wi-Fi Protected Access.
• Provides additional encryption using Temporal Key Integrity Protocol (TKIP).
• TKIP is vulnerable to transmission of arbitrary packets.
• Also vulnerable to decryption of arbitrary packets.
• Obsolete – do not use.
WPA2 (802.11i) • Improvement on WPA.
• Includes stronger encryption (CCMP protocol using AES standard).
• Biggest known vulnerability is choosing a weak password.
• The current best choice for Wi-Fi security.
WPS • Automated mechanism for wireless devices to obtain the Wi-Fi key from the
router.
• Wi-Fi setup is easy and convenient.
• Negotiation can be intercepted and cracked by hacking tools.

12. When implementing wireless security:
• Select WPA2 (even WPA2 personal) over WEP or WPA.
• When possible, use a RADIUS server for wireless authentication.
• If you must use a pre-shared key, make the password complex and change it
regularly.
• Manually enter Wi-Fi passwords into your device, rather than allowing them to
autoconfigure themselves by using WPS.
• If necessary, enter the MAC addresses of all devices that are permitted to connect to
the wireless network into the access point.

14. • If a router is compromised, attacker can use it in a man-in-the-middle attack.
• Like planting a bug in a room to listen in remotely.
• Can also initiate DoS attacks.
• Router must be physically protected first and foremost.
• Theft or tampering with router will result in major network issues.
• Routers are also subject to logical attacks.
• Attacker may attempt to access router using a remote protocol like Telnet/SSH.
• May also try to send excessive or malformed packets to router, causing a DoS.
Router Vulnerabilities

15. • Deploy the router in a secure, locked area.
• Disable all unnecessary services on the router.
• Disable any unnecessary routing protocols.
• Harden the router per the manufacturer's recommendations.
• Use SSH instead of Telnet.
• Create access control lists.
• Require strong authentication for administrator connections.
• Limit number of admin connections, and disconnect inactive sessions.
• Require authentication to a centralized server on higher-end routers.
• Create custom administrative accounts with limited privileges for support personnel.
• Ensure passwords are stored using encryption.
• Forward all security events to a central syslog server.
• Monitor activity on the router, watching for suspicious behavior.
Router Security

16. • Comprehensive solution to secure mobile devices as they connect to network.
• Ensures that these devices are healthy and cannot compromise network.
• Software installed on devices includes:
• Firewall
• VPN client
• Antivirus
• Anti-malware
• Encryption
• Uses client/server security model.
• Central server on network pushes updates to mobile clients and controls access.
• Endpoint security often includes mobile device management (MDM).
Endpoint Security

17. • Various devices enable networking capabilities.
• Often found in server rooms.
• Use the following methods to secure these devices:
• Physically secure all devices against tampering or accidents.
• Lock cabinets and rack doors.
• Use cable locks on laptops and small PCs.
• Mount power adapters, smart jacks, media converters, etc., where they can be easily
monitored and serviced.
• Consider using a "lights out" approach to server management.
• Place non-rack-mountable equipment on boltable trays above the rack floor.
• Route all cables both inside racks and in the ceiling in managed bundles and cable trays.
Physical Devices

18. • Physical and Logical Access Control
• Identification, Authentication, and Authorization
• Identity as a Service
• Authorization Mechanisms
• Access Control Attack Mitigation
Identity and Access Management

19. • Process of allowing only authorized entities to observe/modify/take possession of a
computer system or physical property.
• Subject – entity requesting access:
• Person.
• System.
• Process.
Access Control
• Object – entity being accessed – any resource.
• Limits subject’s access to object using predefined rules/roles/labels.
Subjects Objects

20. Types of Access Control Services
Access Control Service Description
Identification and
Authentication (I&A)
• Provides unique identifier for each authorized subject attempting to access
the object.
• Includes method or methods to ensure identity of subject (authentication).
• Typically administered with Identity Management System and support of a
directory.
Authorization • Determines the capabilities or rights of the subject when accessing the
object.
Audit • Creates a log or record of system activities.
Accountability • Reports and reviews the contents of log files.
• Each subject identifier must be unique to relate activities to one subject.

21. Access Control Services Implementation
Individual/entity attempting to access an object.
Identify
Individual’s identity.
Verify
Rules/roles to see what individual is permitted to do.
Evaluate
Audit trail – write each access attempt and function
performed to log file.
Create
Log to see what was completed when and by whom.

23. • Start with administrative policies.
• Reinforce with technical policies.
• All passwords must be at least seven characters long using three different types of
characters.
• A user's identity must be verified before IT staff can reset that person's password.
• Process to suspend/deactivate user account in case of termination/compromise/infection.
• Inactive user accounts must be disabled after 60 calendar days.
• User account will be locked out for 15 minutes after three bad logon attempts.
• Users can’t have local administrative privileges on their computer unless approved by
manager.
• Existing local administrative privilege will be reviewed annually.
• All administrator accounts must use two-factor authentication to log on to the network.
• All workstations must implement a screen lock after 15 minutes of inactivity.
• Access to administrator systems must be reviewed annually.
• IT staff may not use administrator accounts for general purpose.
Access Control Policies (Slide 1 of 2)

24. • Reinforce with technical policies (Cont.)
• Vendor and contractor access list to be approved, monitored, and limited to the length of
the contract.
• Default administrator passwords must be changed before the system goes into production.
• Default ports for administrator access must be changed when possible.
• Administrative access cannot be accomplished through a public interface.
• Each new user account will receive a unique first-time password that must be changed
upon first use.
• Any reset passwords must be set to unique value for each user and changed upon first use.
Access Control Policies (Slide 2 of 2)

25. Information Access
Logical Access Concern Mitigation
Databases with sensitive information are prime
targets.
• Isolate database from rest of network.
• Use authentication/authorization mechanisms.
Inability to determine who is using remote
connections.
• Implement remote authentication protocols.
All accounts allow full access to data. • Set up varied levels of access permissions.
Physical Access Concern Mitigation
Attackers simply walking out with a bunch of
servers.
• Lock and monitor server rooms/data centers.
Hard copies of sensitive information. • Keep hard copies in locked file cabinets/safes.
