[Certificate]

This subkey stores SSL/TLS certificates configuration values.

DestinationCertPreference

This value is of type REG_SZ, and defines the required level of SSL/TLS certificate verification when connecting to a remote destination server. 

Note: SSL/TLS certificate verification is not relevant if UDP or TCP protocols are used to connect to the destination.

Accepted values are:
ANY - (Default) Require an SSL/TLS certificate to be presented, but accept the certificate even if the chain of trust cannot be authenticated, or the hostname does not match the presented certificate. This is useful for self-signed certificates.
STRICT - Require an SSL/TLS certificate to be presented, and have both a valid chain of trust and also a hostname matching the certificate. A hostname must be provided in the associated Destination#Host setting, as an IP address will not work.

DestinationCertPreferenceSAM

This value is of type REG_SZ, and defines the required level of SSL/TLS certificate verification when connecting to a Snare Agent Manager server. 

Accepted values are:
ANY - (Default) Require an SSL/TLS certificate to be presented, but accept the certificate even if the chain of trust cannot be authenticated, or the hostname does not match the presented certificate. This is useful for self-signed certificates.
STRICT - Require an SSL/TLS certificate to be presented, and have both a valid chain of trust and also a hostname matching the certificate. A hostname must be provided in the SAM1IP setting, as an IP address will not work.

WebCertID

The thumbprint of the certificate to be used for HTTPS web user interface interactions. 

By default, Snare Agent generates a self-signed certificate. Customer is welcome to replace it with a CA-signed certificate for improved security. 

AgentLog

CachePath

This is the disk cache path where the agent will temporarily save all unsent events if the agent needs to restart. Agent will read and send the events on next start.

Checksum

Delimiter

This value is of type REG_DWORD, and determines whether Epilog includes an MD5 Checksum of the contents of each audit record, with the record in question. Set this value to 0 for no, or 1 for Yes. Will default to FALSE (0) if not set. Note that the checking application will need to strip the final delimiter, plus the MD5 Checksum, from the record before evaluating the record against the checksum.

Clientname

This is the Hostname of the client and is of type REG_SZ. If no value has been set, "hostname" command output will be displayed. Must be no more than 100 chars, otherwise will truncate.

strip the final delimiter, plus the MD5 Checksum, from the record before evaluating the record against the checksum.

Clientname

This is the Hostname of the client and is of type REG_SZ. If no value has been set, "hostname" command output will be displayed. Must be no more than 100 chars, otherwise will truncate.

EventSourceId

This is of type REG_SZ and stores the Windows Registry path from where to read the Event Source Id text/value. If the value in EventSourceIdType is 2 (Registry Path), then the text/value in the registry, specified by the path, is included in each event.

EventSourceIdText

This is of type REG_SZ and directly stores the Event Source Id text/value. If the value in EventSourceIdType is 1 (Free Text), then this text/value is included in each event.

EventSourceIdType

This is of type REG_DWORD and stores the option related to specifying Event Source Id: 0(NONE), 1(Free Text), 2(Registry Path).

IISLogFlush

TLS13Minimum

This value is of type REG_DWORD. When disabled (0), Snare Agent supports TLS 1.2 and TLS 1.3 for web connections. When enabled (1), TLS 1.2 is explicitly disabled; browsers connecting to the agent website must support at least TLS 1.3 for ssl connections.

Separator

Legacy agent setting required to upgrade agents (if it was set to be the identifier to separate events). Defunct for v5 as now set in Destination Configuration.

Set this value to 0 for noNo, or 1 for Yes. Will default to FALSE (0) if not set.

This value is of type REG_DWORD and determines whether Snare should use UTC timestamps instead of the local system time when sending events. Set this value to 0 for no, or 1 for Yes. Will default to FALSE (0) if not set.

Filter# 

(where # is a 
serial number)

This section describes the format of the log filtersFilters applied to Log file monitors. Filters are of type REG_SZ , of no greater than 1060 chars.Example: 
Filter1:    (string), and the stored value looks similar to this: 
criticality=1,6,6,6,3,3,0,0,0,0match="*"regex=0state=1uuid=e6a813b4ec27404d-3a9b1843-41b44d58-b8739617-e7df57fbb2b1
Criticality- Format for this string is d25c09f3040c

criticality - ten comma-separated integer values ([0-4],[0-7],[0-7],[0-7],[0-10],[1-10],0,0,0,0. ) representing event criticality for different event formats. First integer is between 0 and 4 that indicates indicating the severity of the event . Critical = 4, Priority = 3, Warning = 2, Information = 1, Clear = 0. in Snare format: 0 - Clear , 1 - Information, 2 - Warning, 3 - Priority, 4 - Critical. Next 3 values are Syslog for each RFC3164, RFC3164 Alt and RFC5424 formats. Syslog values RFC3164 Alt and RFC5424 are copied from Syslog and not used separately. Values 0-7 denote denote Emergency, Alert, Critical, Error, Warning, Notice, Info and Debug, Debugrespectively. CEF is  0 is  0 - 10, 0 is least severe and 10 is most severe. LEEF is  1 is  1 - 10, 1 is least severe and 10 is most severe. Last 4 values 0,0,0,0 are reserved and not in use.eg. criticality=2,5,5,5,7,9,0,0,0,0

match (General Match)  - The General match term is the filter expression, and is defined to be any value which includes DOS wildcard characters. Max length is 512. It can also include regular expressions if 'regex' box is checked. Use = to include matching events, != to exclude matching events. 

eg match="*"

Regex: =0 (Include general string term to match); =1  (Include regex string term to match)

eg. regex=0
match= - a string (if regex = 0) or a regular expression (if regex = 1) to match and INCLUDE. Events matching this filter will be collected. DOS wildcard characters ("*" and "?") can be used when regex = 0, for example: match="*"
or
match!= - a string (if regex = 0) or a regular expression (if regex = 1) to match and EXCLUDE. Events matching this filter will not be collected.
regex - integer indicating whether the match string is a regular expression: 0 - no; 1 - yes
state - an integer representing the state of Filter configuration: 0 - Disabled; 1 - Enabled; 2 - Requiring Service Restart
uuid - a unique 16-byte identifier of this Filter.

See Log Filter Configuration page in this User Guide for more details.
