Figure 5.4: IP Security Menu
3.The IP Security Menu lists five IP Security "masks" along with the selected permit/deny action for each mask.
. Each Security Mask prompt is used to define a specific IP address or range of IP addresses. Each Mask Action prompt is used to select the permit/deny action for the corresponding mask.
b.Masks are listed in order of ascending priority; Mask 1 has the lowest priority, and Mask 5 has the highest priority.
c.Masks have a cumulative effect; high priority masks supersede the effect of lower priority masks.
d.Each IP Address consists of a series of four eight bit numbers. The number 255 is used as a wild card.
Example 1: Deny access to all hosts except 192.1.1.5:
●Security Mask #1: 255.255.255.255
●Mask #1 Action: Deny
●Security Mask #2: 192.1.1.5
●Mask #2 Action: Permit
Since 255 is a wild card, Mask #1 blocks all IP Addresses. Mask #2 then specifically grants access to 192.1.1.5 only.
Example 2: Allow access only by addresses that begin with 192:
● Security Mask #1: 255.255.255.255
