Software Authentication Manager Commands on Cisco IOS XR Software

This chapter describes the Cisco IOS XR software commands used to configure Software Authentication Manager (SAM).

For detailed information about SAM concepts, configuration tasks, and examples, see the Configuring Software Authentication Manager on Cisco IOS XR Software configuration module.

Cisco IOS XR System Security Command Reference

SR-207

sam add certificate

To add a new certificate to the certificate table, use the sam add certificate command in EXEC mode.

sam add certificate filepath location {trust | untrust}

Software Authentication Manager Commands on Cisco IOSXR Software

Syntax Description

Defaults No default behavior or values

Command Modes EXEC

Command History

filepath Absolute path to the source location of the certificate. location Storage site of the certificate. Use one of the following: root, mem, disk0, disk1,

or other flash device on router.

trust Adds the certificate to the certificate table without validation by the Software

Authentication Manager (SAM). To add a root certificate, you must use the trust keyword. Adding a root certificate with the untrust keyword is not allowed.

untrust Adds the certificate to the certificate table after the SAM has vali dated it. Adding

a root certificate with the untrust keyword is not allowed. To add a root certificate, you must use the trust keyword.

Release Modification

Release 2.0 This command was introduced on the Cisco CRS-1. Release 3.0 No modification. Release 3.2 This command was supported on the Cisco XR 12000 Series Router.

Usage Guidelines To use this command, you must be in a user grou p associated with a task group that includes the proper

task IDs. For detailed information about user groups and task IDs, see the Configuring AAA Services on Cisco IOS XR Software module of the Cisco IOS XR System Security Configuration Guide.

For security reasons, the sam add certificate command can be issued o nly from the console or au xiliary port of the networking device; the command cannot be issued from a Telnet connection to any other interface on the networking device.

The certificate must be copied to the network device before it can be added to the certif icate table. If the certificate is already present in the certificate table, the SAM rejects the attempt to add it.

When adding root certificates, follow these guidelines:

• Only the certificate authority (CA) root certificate can be added to the root location.

• To add a root certificate, you must use the trust keyword. Adding the root certificate with the

untrust keyword is not allowed.

Use of the trust keyword assumes that you receiv ed the ne w certif icate from a source that you trust, and therefore have enough confidence in its authenticity to bypass validation by the SAM. One example of acquiring a certificate from a trusted source is downloading it from a CA server (such as Cisco. com) that

SR-208

Software Authentication Manager Commands on Cisco IOSXR Software

sam add certificate

requires user authentication. Another example is acquiring the certificate from a person or entity that you can verify, such as by checking the identification badge for a person. If you bypass the validation protection offered by the SAM, yo u must verify the id entity and integrity o f the certificat e by some other valid process.

Certificates added to the memory (mem) location validate software installed in memory. Certificates added to the disk0 or disk1 location validate software installed on those devices, respectively.

Note If the sam add certificate command fails with a message indicating that the certificate has expired, the

networking device clock may have been set incorrectly. Use the show clock command to determine if the clock is set correctly.

Examples The following example shows ho w to add the certificate found at /bootflash/ca.bin to the certificate table

in the root location without first validating the certificate:

RP/0/RP0/CPU0:router# sam add certificate /bootflash/ca.bin root trust

SAM: Successful adding certificate /bootflash/ca.bin

The following example shows how to add the certificate found at /bootflash/css.bin to the certificate table in the memory (mem) location after validating the certificate:

RP/0/RP0/CPU0:router# sam add certificate /bootflash/css.bin mem untrust

SAM: Successful adding certificate /bootflash/css.bin

For security reasons, the sam delete certificate command can be issued only from the console port of the networking device; the command cannot be is sued from a Telnet connection to any other interface on the networking device.

Use the show sam certificate summary command to display certificates by their index numbers. Because the certificate authority (CA) certificate must not be unknowingly deleted, the Software

Authentication Manager (SAM) prompts the user for confirmati on when an attempt is made to delete the CA certificate.

If a certificate stored on the system is no longer valid (for example, if the certificate has expired), you can use the sam delete certificate command to remove the certificate from the list.

Examples The following example shows how to delete the certificate identified by the index number 2 from the

memory location:

RP/0/RP0/CPU0:router# sam delete certificate mem 2

SAM: Successful deleting certificate index 2

sam prompt-interval

To set the interval that the Software Authentication Manager (SAM) waits after prompting the user for input when it detects an abnormal condition at boot time and to determine how the SAM responds when it does not receive user input within the specified interval, use the sam prompt-interval command in global configuration mode. To reset the prompt interval and response to their default values, use the no form of this command.

sam prompt-interval time-interval {proceed | terminate} no sam prompt-interval time-interval {proceed | terminate}

Software Authentication Manager Commands on Cisco IOSXR Software

Syntax Description

Defaults The default response is for the SAM to wait 10 seconds and then terminate the authentication task.

Command Modes Global configuration

Use the sam prompt-interval command to control the action taken wh en the system detects an exception condition, such as an expired certificate during initialization of the SAM at boot time. The following message appears when the software detects the abnormal condition of a certificate authority (CA) certificate expired:

SAM detects expired CA certificate. Continue at risk (Y/N):

SR-212

The SAM waits at the prompt until you respond or the time interval controlled by the sam prompt-interval command exp ires, whichever is the earlier e vent. If you respond “N” to the pro mpt, the

boot process is allowed to complete, but no packages can be installed.

Cisco IOS XR System Security Command Reference

Software Authentication Manager Commands on Cisco IOSXR Software

The following message appears when the software detects the abnormal condition of a Code Signing Server (CSS) certificate expired:

SAM detects CA certificate (Code Signing Server Certificate Authority) has expired. The validity period is Oct 17, 2000 01:46:24 UTC - Oct 17, 2015 01:51:47 UTC. Continue at risk? (Y/N) [Default:N w/in 10]:

If you do not respond to the prompt, the SAM waits for the specif ied interval to expire, and then it takes the action specified in the sam prompt-interval command (either the proceed or terminate keyword).

If you enter the command with the proceed keyword, the SAM w aits for the specified interval to e xpire, and then it proceeds as if you had given a “yes” response to the prompt.

If you enter the command with the terminate keyword, the SAM waits for the specified interval to expire, and then it proceeds as if you had gi v en a “no” r esponse to the p rompt. This use of the command keeps the system from waiting indefinitely when the system console is unattended.

Note After the software has booted up, the time-interval argument set using this command has no effect. This

value applies at boot time only.

sam prompt-interval

Examples The following example shows how to tell the SAM to wait 30 seconds for a user response to a prompt

and then terminate the requested SAM processing task:

RP/0/RP0/CPU0:router# configure RP/0/RP0/CPU0:router(config)# sam prompt-interval 30 terminate

sam verify

Software Authentication Manager Commands on Cisco IOSXR Software

T o use the Message Digest 5 (MD5) hash algorith m to verify the int egri ty of the softw are component on a flash memory card and ensure that it has not been tampered with during transit, use the sam verify command in EXEC mode.

sam verify {location | file-system} {MD5 | SHA [digest]}

Syntax Description

Defaults No default behavior or values

Command Modes EXEC

Command History

location Name of the flash memory card slot, either disk0 or disk1. file-system Absolute path to the file to be verified.

MD5 Specifies a one-way hashing algorithm to generate a 128-bit hash (or message

digest) of the specified software component.

SHA Specifies the Secure Hash Algorithm, a hashing algorithm that takes a message of

less than 264 bits in length and produces a 160-bit message digest. The large message digest provides security against brute-force collision and inversion attacks.

digest (Optional) Message digest generated by the hashing algorithm, to be compared in

determining the integrity of the software component.

Release Modification

Release 2.0 This command was introduced on the Cisco CRS-1. Release 3.0 No modification. Release 3.2 This command was supported on the Cisco XR 12000 Series Router.

Usage Guidelines To use this command, you must be in a user grou p associated with a task group that includes the proper

task IDs. For detailed information about user groups and task IDs, see the Configuring AAA Services on Cisco IOS XR Software module of the Cisco IOS XR System Security Configuration Guide.

Use the sam verify command to generate a message digest for a given device. The message digest is useful for determining whether software on a flash memory card has been tampered with d uring transit. The command generates a hash code that can be used to compare the integrity of the software between the time it was shipped and the time you received it.

For example, if you are given a flash memory card with preinstalled software and a pre viously generated MD5 message digest, you can verify the integrity of the software using this command:

sam verify device MD5 digest

where device is the flash device and digest is the message digest supplied by the originator of the software.

Cisco IOS XR System Security Command Reference

SR-214

Software Authentication Manager Commands on Cisco IOSXR Software

sam verify

If the message digest matches the message digest generated by the sam verify command, the software component is valid.

Note You should calculate the hash code on the contents of the flash memory code at the destination

networking device using a different set of files from the one loaded on the flash memory card. It is possible for an unauthorized person to use the same software version to produce the desired (matching) hash code and thereby disguise that someone has tampered with the n ew software.

Examples The following example shows how to use MD5 to generate a message digest on the entire file system on

the flash memory card in slot 0 and then use that message digest as input to perform the digest comparison. The example shows a third sam verify command, issued with a mismatched message digest, to show the Software Authentication Manager (SAM) response to a mismatch.

RP/0/RP0/CPU0:router# sam verify disk0: MD5

Total file count in disk0: = 813 082183cb6e65a44fd7ca95fe8e93def6

RP/0/RP0/CPU0:router# sam verify disk0: MD5 082183cb6e65a44fd7ca95fe8e93def6

Total file count in disk0: = 813 Same digest values

RP/0/RP0/CPU0:router# sam verify disk0: MD5 3216c9282d97ee7a40b78a4e401158bd

Total file count in disk0: = 813 Different digest values

The following example shows how to use MD5 to generate a message digest and then uses that messag e digest as input to perform the digest comparison:

RP/0/RP0/CPU0:router# sam verify disk0: /crl_revoked.bin MD5

38243ffbbe6cdb7a12fa9fa6452956ac

RP/0/RP0/CPU0:router# sam verify disk0: /crl_revoked.bin MD5

38243ffbbe6cdb7a12fa9fa6452956ac
