1 Initial Steps

As soon as you suspect a breach, it's vital to verify the incident. Start by reviewing security alerts from your intrusion detection systems (IDS) and firewalls. Check server logs for any unusual activity, such as multiple failed login attempts or unexpected access patterns. It's also important to ensure that your security software is up to date, as outdated systems can miss signs of a breach. This initial investigation can provide clues about the nature and potential source of the attack.

Uno de los pasos iniciales es ser concientes de la brecha de seguridad, como tambien entender desde cuando esta ocurriendo y quien puede ser el origen de la misma. Revisar IPSs, IDSs, Firewalls, logs en busqueda de indicios de un IoC (Indicador de Compromiso) Tambien es importante entender hasta donde llegaron los atacantes para poder contener el ataque

2 Analyze Logs

Log files are the treasure trove of information when tracking down a security breach. Analyze web server, application, and database logs for any anomalies. Look for patterns that indicate a breach, such as IP addresses that repeatedly trigger errors or user accounts that perform actions they're not authorized for. Use log management tools to sift through vast amounts of data efficiently. Time stamps are particularly crucial as they help correlate events across different systems to pinpoint when the breach occurred.

Buscar indicios de ataques provenientes de IoCs (Indicadores de Compromiso) conocidos, publicados con las IPs malciosas de ataques en curso. Revisar logs, revisar registros del firewall Todo esto nos ayudara a entender no solo el origen, sino tambien el alcance de la brecha de seguridad.

3 Network Check

Monitoring network traffic is essential in identifying a breach source. Utilize network monitoring tools to observe outgoing and incoming traffic. Look for unexpected spikes or unusual data packets that could signify data exfiltration or command and control (C2) communications with an attacker's server. Pay special attention to traffic that bypasses typical security checkpoints or originates from unrecognized IP addresses, as these can be red flags for malicious activity.

4 System Audit

Perform a thorough system audit to check for any unauthorized changes. Examine user accounts for new or altered permissions and review installed software and system configurations for unexpected modifications. Attackers often leave behind tools or scripts that can provide clues about their methods and origins. Ensure that all patches and updates have been applied, as unpatched vulnerabilities are common entry points for attackers.

5 User Activity

User behavior analytics can be instrumental in detecting security breaches. Monitor user activity for actions that deviate from typical patterns. This may include accessing sensitive data at unusual times or downloading large volumes of information. High-risk user actions, such as disabling security features or attempting to access restricted areas, should raise immediate red flags and warrant further investigation.

Verificar si algun usuario en particular tiene un comportamiento no habitual, en especial administradores, ya que puede haber sido vulnerada su cuenta y el atacante comenzar un reconocimiento de nuestra red

6 Engage Experts

If pinpointing the source of the breach proves challenging, don't hesitate to engage cybersecurity experts. These professionals have the experience and tools necessary to conduct a deep forensic analysis. They can help identify advanced persistent threats (APTs) and sophisticated malware that may be hiding in your systems. Their expertise can accelerate the discovery process and aid in developing a robust response plan to prevent future incidents.

Es fundamental involucrar a profesionales con experiencia en este tipo de incidentes, probablemente, quienes tenemos experiencia en nuestro dia a dia en ayudar a empresas que sufren brechas de seguridad tengamos mas probabilidades de encontrar parametros, como asi tambien poder brindar ayuda elaborando un plan de accion a seguir. No se debe intentar resolver solo al problema, ya que el tiempo es fundamental
