Serverless Incident Response

Serverless architectures present unique challenges:

Lambda Function Analysis:

import boto3

def analyze_lambda_execution(function_name):
    logs = boto3.client('logs')
    lambda_client = boto3.client('lambda')
    
    # Get function configuration
    config = lambda_client.get_function_configuration(
        FunctionName=function_name
    )
    
    # Analyze CloudWatch logs
    log_group = f'/aws/lambda/{function_name}'
    streams = logs.describe_log_streams(
        logGroupName=log_group,
        orderBy='LastEventTime',
        descending=True
    )
    
    for stream in streams['logStreams']:
        events = logs.get_log_events(
            logGroupName=log_group,
            logStreamName=stream['logStreamName']
        )
        # Analyze events for anomalies
