🚨 High Priority Tasks (24-48 Hours)

Task 1: Disable HTTP Server

Risk: Unencrypted management access exposes credentials to eavesdropping

Commands:

configure terminal
no ip http server
end
write memory

Verification:

show ip http server status

• Execute remediation
• Verify configuration
• Update documentation

---

Task 2: Disable IP Source Routing

Risk: Allows routing attacks and packet spoofing

Commands:

configure terminal
no ip source-route
end
write memory

Verification:

show running-config | include ip source-route

• Execute remediation
• Verify configuration
• Update documentation

---

⚠️ Medium Priority Tasks (1-2 Weeks)

Task 3: Configure Centralized Logging

Risk: Security events and audit trails lost without remote logging

Commands:

configure terminal
logging host <SYSLOG-SERVER-IP>
logging trap informational
logging facility local7
logging source-interface <MGMT-INTERFACE>
end
write memory

Verification:

show logging

• Identify syslog server IP
• Execute remediation
• Verify logs arriving at syslog server
• Update documentation

---

Task 4: Configure NTP

Risk: Inaccurate timestamps affect AAA logs and certificate validation

Commands:

configure terminal
ntp server <NTP-SERVER-IP> prefer
ntp authenticate
ntp authentication-key 1 md5 <KEY>
ntp trusted-key 1
ntp update-calendar
end
write memory

Verification:

show ntp status
show ntp associations

• Identify NTP server IP and authentication key
• Execute remediation
• Verify time synchronization
• Update documentation

---

Task 5: Disable TCP/UDP Small Servers

Risk: Legacy services exploitable for reconnaissance and DoS attacks

Commands:

configure terminal
no service tcp-small-servers
no service udp-small-servers
no service pad
end
write memory

Verification:

show running-config | include service

• Execute remediation
• Verify configuration
• Update documentation

---
