Functions

func AdapterFactory added in v1.5.1 

func AdapterFactory(parser LogParser) pantherlog.FactoryFunc

AdapterFactory returns a pantherlog.LogParserFactory from a parsers.Parser This is used to ease transition to the new parsers.Interface for parsers based on parsers.PantherLog

func AppendAnyString added in v0.2.0 

func AppendAnyString(any *PantherAnyString, values ...string)

func CsvStringToArray added in v0.2.0 

func CsvStringToArray(value string) []string

func CsvStringToFloat64Pointer added in v0.2.0 

func CsvStringToFloat64Pointer(value string) *float64

func CsvStringToInt16Pointer added in v0.2.0 

func CsvStringToInt16Pointer(value string) *int16

func CsvStringToIntPointer added in v0.2.0 

func CsvStringToIntPointer(value string) *int

func CsvStringToPointer added in v0.2.0 

func CsvStringToPointer(value string) *string

func LooksLikeCSV added in v1.5.0 

func LooksLikeCSV(log string) bool

Returns true if log looks like a CSV log. It can be used to fail fast for logs that are not CSV

func NewAdapter added in v1.5.1 

func NewAdapter(parser LogParser) pantherlog.LogParser

NewAdapter creates a pantherlog.LogParser from a parsers.Parser

func NewValidator added in v1.7.0 

func NewValidator() *validator.Validate

NewValidator creates a validator.Validate instance that knows how to handle the types used in panther logs.

Types

type Interface added in v1.5.1 

type Interface = pantherlog.LogParser

Interface is the interface to be used for log parsers.

type LogParser 

type LogParser interface {
	// LogType returns the log type supported by this parser
	LogType() string

	// Parse attempts to parse the provided log line
	// If the provided log is not of the supported type the method returns nil and an error
	Parse(log string) ([]*PantherLog, error)

	// New returns a new instance of the log parser, used like a factory method for stateful parsers
	New() LogParser
}

LogParser represents a parser for a supported log type NOTE: We will be transitioning parsers to the `parsers.Interface` interface. Until all parsers are converted to the new interface the `AdapterFactory()` helper should be used when registering a new log type to a `logtypes.Registry`

type PantherAnyString added in v0.2.0 

type PantherAnyString []string

func (PantherAnyString) MarshalJSON added in v0.2.0 

func (any PantherAnyString) MarshalJSON() ([]byte, error)

type PantherLog added in v0.2.0 

type PantherLog struct {

	//  required
	PantherLogType     *string            `json:"p_log_type,omitempty" validate:"required" description:"Panther added field with type of log"`
	PantherRowID       *string            `json:"p_row_id,omitempty" validate:"required" description:"Panther added field with unique id (within table)"`
	PantherEventTime   *timestamp.RFC3339 `json:"p_event_time,omitempty" validate:"required" description:"Panther added standardize event time (UTC)"`
	PantherParseTime   *timestamp.RFC3339 `json:"p_parse_time,omitempty" validate:"required" description:"Panther added standardize log parse time (UTC)"`
	PantherSourceID    *string            `json:"p_source_id,omitempty" description:"Panther added field with the source id"`
	PantherSourceLabel *string            `json:"p_source_label,omitempty" description:"Panther added field with the source label"`

	// optional (any)
	PantherAnyIPAddresses  PantherAnyString `json:"p_any_ip_addresses,omitempty" description:"Panther added field with collection of ip addresses associated with the row"`
	PantherAnyDomainNames  PantherAnyString `json:"p_any_domain_names,omitempty" description:"Panther added field with collection of domain names associated with the row"`
	PantherAnySHA1Hashes   PantherAnyString `json:"p_any_sha1_hashes,omitempty" description:"Panther added field with collection of SHA1 hashes associated with the row"`
	PantherAnyMD5Hashes    PantherAnyString `json:"p_any_md5_hashes,omitempty" description:"Panther added field with collection of MD5 hashes associated with the row"`
	PantherAnySHA256Hashes PantherAnyString `` /* 144-byte string literal not displayed */
	// contains filtered or unexported fields
}

All log parsers should extend from this to get standardized fields (all prefixed with 'p_' as JSON for uniqueness) NOTE: It is VERY important that fields are added to END of the structure to avoid needed to re-build existing Glue partitions.
