1. MDM PKI Interface with SSM

In order to setup, query and remove the Ipsec/IKE and PKI on the local workstation, both MDM and SSM will manipulate the solaris IP security database. The interface between MDM and SSM is mainly on the Solaris Ipsec IKE and PKI config files and its daemon. The behaviours of MDM and SSM manipulation are compatible with Solaris standard in term of the file format and patterns used.

1.1 Provisioning Interface

1.1.1 ike.config

The /etc/inet/ike/config file, which is configuration file for IKE policy, contains rules for matching inbound IKE requests. It also contains rules for preparing outbound IKE requests.

The ike.config is the most important interface between MDM and SSM:

· Either MDM or SSM could create, duplicated, append, removal, chmod etc.

· MDM will create this file if it does not exist (at IKE preshared key), else, it will append/edit it.

· SSM could create it for MDM at rsasig if it does not exit.

· Shared the items definition and values

1.1.1.2 Interaction details

ike.config items	definition	Interaction details/Issues	Solution
Global parameters shared by MDM and SSM
p1_nonce_len 20	Nonce length of Phase1 negotiation	MSS requires 20 for MDM-MSS IKE rsasig relationship. SSM sets it to 40 as SPFS required.	MDM forces it to 20 SSM must not overwrite it if it’s not null.
cert_root "CN=PKBRoot01, ST=North Carolina, C=US, L=Research Triangle Park, O=Security, OU=3X20" cert_trust "CN=PKBRoot01, ST=North Carolina, C=US, L=Research Triangle Park, O=Security, OU=3X20"	cert_root and cert_trust required for MDM/MSS IKE rsasig. .

p1_lifetime_secs 28800	IKE phase1 SAs lifetime, it’s global and could be override by values in the rule entry	SSM sets it to 28800, MDM requires 86400 by default.	If does not exist, MDM will append that item with 86400. No matter the value, MDM sets p1_lifetime to 86400 per IKE rule locally.
SSM appended entries ( for instance, default phase1 xform)
p1_xform { auth_method preshared oakley_group 1 auth_alg sha encr_alg 3des } p2_pfs 0	# ## Defaults that individual rules can override.	Added by SSM. It is from SSPFS installation	No action required for MDM

local_id_type dn	The local id type, “dn” means the DNX.509 distinguished name	No action required for SSM SSM should not touch it.	MDM always set it to “dn” if at rsasig.
local_addr 47.154.135.86	local IP address
local_id "CN=SSM0 47.154.135.86, ST=North Carolina , C=US, L=Research Triangle Park, O=Security, OU=3X20"	The DNX.509 distinguished name	SSM must modify it when MDM certs were replaced/revoked.	MDM sets its value firstly by retrieving it from the local workstation Removed by MDM when delete IKE rules
remote_addr 47.154.136.69	IP address of the remote entry with IPv4 format	No action required for SSM. SSM should not touch it.	Set by MDM
remote_id ""	Use remote_addr for access control. when null means “take any”	No action required for SSM SSM should not touch it.	Set by MDM

1.1.1.3 Scenario 1: Create ike.config if does not exist

The in.iked refuses to start if this file is missed.

MDM ike scripts will create this file at first with permission 755 if it does not exist.

SSM will create this file when putting data to it( such as generate/install certs)

1.1.1.4 Scenario 2: IKE PSK only

Here is the sample file after MDM Ike phase1 provisioned with preshared:

p1_lifetime_secs 86400
p1_nonce_len 20
########
{
label INDEXID_1
local_id_type ip
local_addr 47.154.135.86
remote_addr 47.154.136.69
p2_pfs 2 p2_lifetime_secs 28800
p1_xform { auth_method preshared oakley_group 2 auth_alg md5 encr_alg 3des}
}

1.1.1.5 Scenario 3 : certs installed by SSM when IKE PSK already provisioned

If the ike phase1 preshared key provisioned already, using the SSM GUI to generate and install certs for MDM, here is the ike.config should look like:

#
## Defaults that individual rules can override.
p1_xform
{ auth_method preshared oakley_group 1 auth_alg sha encr_alg 3des }
p2_pfs 0

--->The following is used by MDM:

#
{
label INDEXID_1
local_id_type ip
local_addr 47.154.135.86
remote_addr 47.154.136.69
p2_pfs 2 p2_lifetime_secs 28800
p1_xform { p1_lifetime_secs 86400 auth_method preshared oakley_group 2 auth_alg md5 encr_alg 3des}
}
~

1.1.1.6 Scenario 4: IKE rsasig provisioned from none security

Here is the example if the MDM IKE rsasig provisioned from none security

p1_nonce_len 20
## Global parameters
cert_root "CN=PKBRoot0000, ST=North Carolina, C=US, L=Research Triangle Park, O=Security, OU=3X20"

p1_xform { p1_lifetime_secs 86400 auth_method rsa_sig oakley_group 2 auth_alg sha1 encr_alg des}
}

1.1.1.7 Scenario 5: IKE transition from PSK to rsasig

The config file, ike.config used the same as the IKE rsasig provisioned from none security

1.1.1.8 Scenario 6: IKE rsasig with IKE PSK co-existence

IKE PSK and IKE rsasig together after MDM ike phase1 provisioned, Here the IKE rsasig and preshared rule refers to the different remote entries

1.1.2 Public keys used by MDM

Public keys used by MDM are stored at /etc/inet/ike/publickeys

The /etc/inet/ike/publickeys directory contains the public part of a public-private key pair and its certificate in files, or “slots”, which is protected at 0755(not changeable other than root). The “ikecert certdb” command to populate the directory.

MDM ike_add_phase1 (at rsasig mode) will check the existence of the public keys by /usr/sbin/ikecert certdb –l before it’s going further on the config of IKE phase 1 rules.

This dir is filled by SSM when generation certs for MDM.

These files should get updated by SSM if the certs were replaced /deleted.

1.1.3 Private keys used by MDM

MDM’s private keys are stored at /etc/inet/secret/ike.privatekeys.

The ike.privatekeys directory holds private key files that are part of a public-private key pair, keying material for ISAKMP SAs. The directory is protected at 0700. The private key in this database must have a public key counterpart in the publickeys database.The ikecert certlocal command populates this directory. Private keys are not effective until their public key counterparts, self-signed certificates or CAs, are installed in the /etc/inet/ike/publickeys directory.

MDM application does not populate it explicitly, it relies on the SSM at the succession PKI framework (with CM) to own it(create/remove and permission).

This dir is filled by SSM when generation certs for MDM.

These files should get updated by SSM if the certs replaced/deleted.

1.1.4 in.iked

in.iked is the Solaris ike daemon shared by MDM, SSM so far.

In order to get the privilege to manipulate the IKE database, when provisioning IKE between MDM and MSS such as adding ike phase1 and removal of them. MDM would restart the in.iked with privilege 2if it’s not running or running without proper right.

1.1.4.1 To get the privilege:

"/usr/sbin/ikeadm get priv",

The privilege level should be 2(can access keying materials), if not, MDM will kill and start it again.

1.1.4.2 To kill it:

/usr/bin/pkill in.iked

1.1.4.3 To start it:

IKE daemon is started with privilege 2 as the following:

/usr/lib/inet/in.iked -p 2

1.1.5 ipsec config file

The ipsecconf file, located at /etc/inet/ipsecinit.conf, is shareable between MDM and SSM.

At MDM: Used for manual key SAs config (mdm_pki_initial and ipsec***) and IKE phase2 policies

At SSM: Used for config IKE phase 2 policies

SSM is enhanced to support the 2 patterns of ipsec policy entry: pattern1 and pattern2, so the Ipsec policies, provisioned by MDM, will be displayed correctly at SSM GUI.

These two ipsec policy entry: pattern1 and pattern as:

         pattern_name_value_pair1 ::=

             saddr <address>/<prefix> |

             src <address>/<prefix> |

             srcaddr <address>/<prefix> |

             smask <mask> |

             sport <port> |

             daddr <address>/<prefix> |

             dst <address>/<prefix> |

             dstaddr <address>/<prefix> |

             dmask <mask> |

             dport <port> |

             ulp <protocol> |

             proto <protocol>

          pattern_name_value_pair2 ::=

             raddr <address>/<prefix> |

             remote <address>/<prefix> |

             rport <port> |

             laddr <address>/<prefix> |

             local <address>/<prefix> |

             lport <port> |

             ulp <protocol> |

1.1.6 ipseckeys

Ipsec Keys, one of the config file for manual Ipsec, located at /etc/inet/secret/.

SSM does not make use of it since it does not support manual key Ipsec. MDM manipulates it as the following MDM scripts:

PKI involved (used for protection TCP829 for CMP messages)

· mdm_pki_initial_script

· pki_decommissioning_script

The example of the /etc/inet/secret/ipseckeys after the mdm_pki_initial looks like:

For phase1: enc_alg = 3des, auth_alg = sha1, DHG_Group =2

For phase2: enc_alg = aes, auth_alg= md5 (for ftpdata) or sha1(others), DHG_group=2

2.2 Provisioning Interface

The provisioned interface with MSS is via CAS of the MSS, which will manipulate the components and their attributes, please refer [3] for more. Here is the description on the command used for MDM IKE provisioning scripts:

2.2.1 Procedure to add initial PKI relationship

Before the IKE_Add_Phase1 is executed, the operator should ensure the ipsec feature installed on MSS, that is:

Here lists the steps to add PKI at MSS part below:

It takes the example as MSS OAM port with IPaddress <RemoteAddress>, and MDM1 with IPaddress <MDMAddress1>, MDM2 with IPaddress <MDMAddress2> for redundancy.

These steps should be put in pki_initial_script.

add -s vr/0 ip pmm ip <RemoteAddress>

set vr/0 ip pmm ca/1 ip <MDMAddress1>

add -s vr/0 ip pmm ca/2 ip <MDMAddress2>

# for ssh from the two mdms

add -s vr/0 ip spd/1 pol/10 dport 22, action bypass, proto tcp, saddr <MDMAddress1>, daddr <RemoteAddress>

add -s vr/0 ip spd/1 pol/20 sport 22, action bypass, dir out, proto tcp, daddr <MDMAddress1>, saddr <RemoteAddress>

add -s vr/0 ip spd/1 pol/30 dport 22, action bypass, proto tcp, saddr <MDMAddress2>, daddr <RemoteAddress>

add -s vr/0 ip spd/1 pol/40 sport 22, action bypass, dir out, proto tcp, daddr <MDMAddress1>, saddr <RemoteAddress>

# for pki messaging from the two mdms

add -s vr/0 ip spd/1 pol/100 proto tcp, sport pki, saddr <MDMAddress1>, daddr <RemoteAddress>

add -s vr/0 ip spd/1 pol/101 proto tcp, dport pki, daddr <MDMAddress1>, saddr <RemoteAddress>

add -s vr/0 ip spd/1 pol/102 proto tcp, sport pki, saddr <MDMAddress2>, daddr <RemoteAddress>

add -s vr/0 ip spd/1 pol/103 proto tcp, dport pki, daddr <MDMAddress2>, saddr <RemoteAddress>

# added the ipsec SAs for the two em_pmm mdms

a -s vr/0 ip spd/1 pol/100 sa/<RemoteAddress>,esp,700

a -s vr/0 ip spd/1 pol/101 sa/<MDMAddress1>,esp,701

a -s vr/0 ip spd/1 pol/102 sa/<RemoteAddress>,esp,702

a -s vr/0 ip spd/1 pol/103 sa/<MDMAddress2>,esp,703

set vr/0 ip spd/1 pol/100 sa/<RemoteAddress>,esp,700 manespsa encAlg aes, encKey <key>, authAlg sha1, authKey <key>

set vr/0 ip spd/1 pol/101 sa/<MDMAddress1>,esp,701 manespsa encAlg aes, encKey <key>, authAlg sha1, authKey <key>

set vr/0 ip spd/1 pol/102 sa/<RemoteAddress>,esp,702 manespsa encAlg aes, encKey <key>, authAlg sha1, authKey <key>

set vr/0 ip spd/1 pol/103 sa/<MDMAddress2>,esp,703 manespsa encAlg aes, encKey <key>, authAlg sha1, authKey <key>

2.2.2 Add ike with rsasig

These steps should be handled by IKE_Add_Phase1 and IKE_MSS_Commissioning

The operator would provide the <RemoteAddress> and the <authMethod> (RSA_SIG) in the Commandline.

# Add IKE bypass policies

add -s vr/0 ip spd/1 pol/50 proto udp, dport ike, action bypass, saddr <MDMAddress1>, daddr <RemoteAddress>

add -s vr/0 ip spd/1 pol/60 proto udp, sport ike, action bypass, daddr <MDMAddress1>, saddr <RemoteAddress>, dir out

add -s vr/0 ip spd/1 pol/70 proto udp, dport ike, action bypass, saddr <MDMAddress2>, daddr <RemoteAddress>

add -s vr/0 ip spd/1 pol/80 proto udp, sport ike, action bypass, daddr <MDMAddress2>, saddr <RemoteAddress>, dir out

# Add IKE with the ip address of the OAM port on mss

add -s vr/0 ip spd/1 ike srcIpAddress <RemoteAddress>

# add pkiClient, also link the pki to pmm

add -s vr/0 ip spd/1 ike pki,linkToPmm Vr/0 Ip Pmm

# link ike policy to pkiClient and set the destination ip address of the Ike policy

set Vr/0 Ip Spd/1 Ike Policy/1 linkToPkiClient vr/0 ip spd/1 ike pki, dest <MDMAddress1>

# refer the Policy to ike Proposal with rsaSig

set vr/0 ip spd/1 ike pol/1 pfs on

set Vr/0 Ip Spd/1 Ike Policy/1 ikeProposal Vr/0 Ip Spd/1 ike Proposal/1

(The one default proposal is automatically added under ike)

set vr/0 ip spd/1 ike prop/1 trans/1 authMethod rsaSig

(The one default transform is also added automatically)

2.2.3 IKE Phase2 provisioning

IKE phase2 provisioned as normal, IKE_add_phase2 would be invoked to do that: e.g. below is for any-any ipsec (phase 2)

a -s vr/0 ip spd/1 pol/200 action apply, dir inbound, ikePolicy Vr/0 Ip Spd/1 Ike Policy/1, srcIpAddress <MDMAddress1>, dstIpAddress <RemoteAddress>

a -s vr/0 ip spd/1 pol/201 action apply, dir outbound, ikePolicy Vr/0 Ip Spd/1 Ike Policy/1, srcIpAddress <RemoteAddress>, dstIpAddress <MDMAddress1>

a -s vr/0 ip spd/1 prop/1 ipSecPolicyList vr/0 ip spd/1 pol/200 vr/0 ip spd/1 pol/201

s Vr/0 Ip Spd/1 Proposal/1 Transform/1 diffieHellmanGroup gp1, antiReplay on

2.3 Messages Format and Walk through

The message Interface residents within MDM EM_PMM, its south-bound named MSS PMM, and the north bound is CM.

The messages that are supported between EM PMM and MSS PMM are the following:

· Certification Request

· Certification Response

· Key Recovery Request

· Key Recovery Response

· Error Message

· Confirmation

· Certificate Announcement

Please refer NM0542 Design Specification [5] for more of the CMP messages definition.

2.4 IKE stack interactive between Solaris and MSS

MSS communicate with Solaris IKE where MDM residents directly, MDM does not change the behaviour, however, since the limitation of the Solaris IKE implementation, there are two interactive issues found and addressed:

2.4.1 IKE SA flush

During the IKE negotiation, the remote entity will reset their SAs and yet the local Solaris maintains the existing SAs until they have expired). When the connection with MSS is lost, the local Phase2 SAs should be flushed as well as the phase1 SA.

As a result of that, SFM is enhanced to monitor the connections using ping against with all remote IKE entries, SFM identifies the remote entries through IKE phase1 SAs or phase2 SAs, then ping them one by one. If un-pingable, the local SAs will be flushed via ike_sa_refresh. The traffic will trigger the re-negotiation of SAs automatically when needed.

It applies to IKE both rsasig and preshared.

2.4.2 in.iked restarted

The solaris in.iked still refers to the old certs information when the device certs got replaced either from CM GUI or MSS. That will cause the authentication failure for IKE phase1 negotiation, as the result of that, the datapath will be down after the phase2 SAs expiration.

The solution is to restart in.iked at MDM each time the device certs got replaced. (CM/SSM has restarted the in.iked when revoked the MDM certs).

1. MSS sends CMP error with 123321 error code to indicate the MSS certs replacement occurred, thus the ike daemon at MDM is required to be restarted.

2. MDM receives the CMP error message then restarts the in.iked

3. At the redundant MDM, since there is no CMP error message arrived, the SFM is enhanced to take this action (restart in.iked) when the remote is unreachable.

3. MDM PKI Interface with CM

When talking about the PKI interface with CM, MDM acts as the proxy CA to MSS,

3.1 Provisioning Interface

None

3.2 Application Programming Interface

See details for pkclient.jar within path com.nortel.sspfssec.pkclient, which is the distribution part of the CM.

See Table 20, Table 21 at CM DSUM [6] page 120 and Page 121.

EM_PMM will communication with CM via it’s distribution part: PKBClient, Please refer NM0542 Design Specification [5] for more of the CMP messages definition.

4. MDM PKI Interface with Solaris

4.1 Provisioning Interface

The provisioning interface, is for the config files of Solaris IP security, see above on MDM PKI interface with SSM.

4.2 Application Programming Interface

4.2.1 ikeadm

The ikeadm utility retrieves information from and manipulates the configuration of the IKE protocol daemon, which is the interface for IKE polices database as well.

Here is the command used by ike provisioned scripts and the argues (please see Solaris man page for details):

/usr/sbin/ikeadm get priv

/usr/sbin/ikeadm dump rule

/usr/sbin/ikeadm get rule <id>

/usr/sbin/ikeadm del rule <id>

/usr/sbin/ikeadm write rule /etc/inet/ike/config

/usr/sbin/ikeadm read preshared /etc/inet/secret/ike.preshared

/usr/sbin/ikeadm write preshared /etc/inet/secret/ike.preshared

/usr/sbin/ikeadm del preshared <srcAddr> <dstAddr>

/usr/sbin/ikeadm get preshared <srcAddr> <dstAddr>

/usr/sbin/ikeadm get p1 <srcAddr> <dstAddr>

/usr/sbin/ikeadm del p1 <srcAddr> <dstAddr>

/usr/sbin/ikeadm get stats <srcAddr> <dstAddr>

4.2.2 ikecert certdb

To get the local DNX509 cert information:

“/usr/sbin/ikecert certdb –l -v“, then get the subject-name from the “CA: FALSE” flagged entry.

4.2.3 ipsecconf

Ipsecconf is used to config Solaris system wide Ipsec policies. MDM uses it with the following way:

/usr/sbin/ipsecconf

/usr/sbin/ipsecconf -l -n

/usr/sbin/ipsecconf -f

/usr/sbin/ipsecconf -a /etc/inet/ipsecinit.conf

/usr/sbin/ipsecconf -d <indexId>

4.2.4 ipseckey

Ipseckey is used to manipulate the Ipsec SA database. MDM uses it as:

/usr/sbin/ipseckey -f /etc/inet/secret/ipseckeys

/usr/sbin/ipseckey -s /etc/inet/secret/ipseckeys

/usr/sbin/ipseckey get esp spi <spi> dst <dstAddr>

/usr/sbin/ipseckey delete esp spi <spi> dst <dstAddr>

/usr/sbin/ipseckey dump
