Sua organização sofreu uma perda de dados. Como evitar que isso aconteça novamente?

In addition to understanding the cause of the incident it is important to understand the root cause. Make sure to identify both corrective and preventive actions. Corrective actions to correct the incident and preventive actions to avoid reoccurance.

Develop orderly backup strategies and keep updating your records over time. Therefore, your backup plan needs to have each type of data and the corresponding back up schedule. Again, make sure that you do periodical testing of your backups for credibility. Encrypt sensitive data to enhance its security against an unwarranted breach. Use anti-virus and anti-malware programs on your systems, so as to curb such threats that ultimately result into a loss of data. Introduce a “no food or drink” policy near company computers, reducing the risks of unintentional data leaks. Destroy appropriately every time such sensitive data is redundant. Put access controls that allow people with a need for access only.

First step is to identify what happened in an objective calm way. Dont play the blame game or jump to conclusions. Find out what happened and verify it via logs / alerts etc. to have concrete evidence. Being calm at this sage is essential so that the relevant data can be gathered. The more information you have about the root cause .. the easier it will be to defend against later and prevent another incident !

Here are some best practices to help ensure successful data loss prevention: Identify and classify sensitive data: To protect your data, you need to know what you’ve got. Use your DLP policy to identify and classify important data across your hybrid environment. Use data encryption: Encrypt data that is at rest or in transit so unauthorised users won’t be able to access it. Prevent data loss: Help people in your organisation to avoid accidental oversharing of sensitive information. Govern your data: Retain, delete, and store data and records in a compliant manner. It’s also important to follow information protection and governance best practices to help your organisation understand, safeguard, and govern its data.

After a data loss, learn from it to stop it happening again. Improve security measures like strong passwords and firewalls. Train everyone about data safety. Limit who can access sensitive info. Back up data regularly. Use security software and update it. Keep an eye on unusual activities. Report and fix problems fast. Learn and adapt from each mistake to make things safer.

Use 321 backup method. You should have 3 backups, in 2 different locations at least, 1 of them is offline. This way would help if a lot and makes your data retrievable in different ways.

In the aftermath of a data loss incident, the swift and effective restoration of systems and information from backups is paramount. Identify the most recent, uncompromised backup and initiate the restoration process, ensuring data integrity and completeness. Prioritize critical systems and sensitive information, adhering to a pre-established recovery plan. Conduct thorough testing to verify the accuracy and functionality of the restored data. Simultaneously, address the root causes of the data loss to prevent future occurrences, fortifying the organization's resilience against potential threats. The timely and meticulous restoration from backups minimizes downtime and is a crucial component of a comprehensive incident response strategy.

Always backup your data frequently. They are the only thing that can save you or break you in case of data loss. So Backup your data

Tão importante quando a restauração do backup é garantir que a falha foi corrigida. Primeiro é preciso garantir que o valor da falha foi identificado e mitigado, a partir dessa conclusão é que as rotinas de restauração devem entrar em cena. Isso é essencial para permitir que o time consiga identificar o momento que houve o comprometimento e agir de acordo na própria mídia de backup, para quando o for provisionado para produção, já tenha sido tratado e não tenha o vetor de ataque exposto novamente.

In my experience, to prevent data loss from Cyber Attacks , every organization should have these basic elements like Strong Password, MFA, Antivirus,Controls for Data at rest and Data in Transit, along with latest patches for all apps/Softwares. Also your security awareness should be strong enough as per the latest attack trends.

One of the major reasons for Cyber Attacks are, non identification of the vulnerabilities and timely patching of the identified vulnerabilities. As a cybersecurity team I would take preventive measures along with reactive measures to maintain a strong Cybersecurity posture to avoid dataloss due to cyber attacks.

Implementing robust security measures involves a strategic approach. Strengthen access controls, deploy encryption protocols, and enforce multi-factor authentication. Regularly update policies, conduct employee training, and monitor systems for vulnerabilities. Collaborate with cybersecurity experts, engage in continuous improvement, and adhere to legal compliance. By integrating these measures, organizations can fortify their defenses, proactively mitigate risks, and create a resilient cybersecurity framework to safeguard against evolving threats.

To prevent your company from future data losses might looks like a complex topic, due to the several attack vectors hackers could use. Therefore, you should implement a diverse setting of measures e.g. regularly back up your data, implement a reliable security infrastructure, train employees in security awareness, and strictly enforce security policies. At the same time it is crucial to keep software and systems up to date and restrict access rights. #ZeroTrust

Start with asking the basic question of what are my Crown Jewels? What digital assets in my organization need to be protected and its nonnegotiable. One you have identified those critical assets, then formulating a short term, mid term and long term strategy can begin.

Regularly reviewing policies and procedures is essential for maintaining an effective security posture. Evaluate the relevance of existing protocols, identify gaps, and ensure alignment with industry best practices. Engage stakeholders for input and updates, and adapt policies to address emerging threats. This ongoing review process ensures that security measures remain robust, compliant, and responsive to the dynamic landscape of cybersecurity, enhancing the organization's resilience against potential risks.

Data loss happens differently in different tools and applications. The policies and procedures must be written in a way that makes them effective with most types of applications and tools. Establishing a DLP policy involves identifying and classifying important data across your hybrid environment, applying protective actions like encryption and access restrictions, and helping people in your organization avoid accidental oversharing of sensitive information.

Your policies and by extension your policy documents are living documents, they should be updated, referred and reflected on regularly by your technical teams as well as Senior Management.

We need to have proper security measures in place while we are taking a backup. -We need to perform regular health checks of our backup devices to prevent any drive failure which has to be replaced in time to prevent data loss. - we need have cross replications between storage devices at different locations. - we need to make sure to have 2 sets of of backups on disk and another backup on tapes where we can retrieve the data from either disk or worst case scenario Tapes. On the whole we need to plan our backup environment in such a way that we have 2 copies of data backed up and a third on tapes and we also need to ensure we have proper security encryption in place to prevent data loss or malware attacks.

In the event of data loss, leveraging data recovery software can be a swift and effective solution. Identify reputable software tools, follow their step-by-step recovery processes, and prioritize the retrieval of critical files. Carefully select software compatible with your system, and regularly back up recovered data to prevent future losses. While data recovery software can be a powerful ally, it's crucial to act promptly and systematically to maximize its effectiveness in restoring lost information.

To strengthen your organizations capabilities in short term, it is advisable to engage an Incident Response Team. Such a team is specifically trained to respond to security incidents, identify potential threats, take countermeasures, and minimize the impact. This helps to limit damage and enhance overall security.

7- Cultivate a Culture of Security Awareness: Beyond technical measures, fostering a culture where every employee is aware of and committed to data security is crucial. Regular training sessions, cybersecurity drills, and awareness campaigns can instill a sense of responsibility and vigilance among staff.

Maintain the contacts of the best data recovery professionals or companies available, in hand and updated, for fast response in case of data loss.

Management and leadership often overlook the importance of awareness and education of staff (especially non-IT staff) you cannot buy your way out of a cybersecurity crisis, only a whole of organization approach will provide the optimal results.

Key points to consider : 👉Being proactive in hunting threats is something you can do to prevent a good range of attacks. 👉Automate the basic tasks to prevent overloading your team. 👉In IR cycles the last step is the famous lesson learned meeting. take these meetings very seriously and take action based on what you have learned from the incidents. 👉After fully recovering from the incident, start correcting your previous causes. 👉DRP and BCP plans can help reduce the cost of outage.

Educate. It is quite likely that a human was somehow involved and educating all of the involved parties (system owners, managers, IT, etc...) will help to minimize the same type of occurrence in the future. The most impenetrable systems are easily defeated by poor human judgement.

Make sure to differentiate between incident response and disaster recovery measures. It is one part to ensure that there is a sufficient amount of measures implemented in order to reduce the probability of cyber attacks, but it could be even more important to ensure that there is a plan in place in case there is a real cyber attack ongoing. It is known that such a situation is a psychological and professional challenge and you need to ensure that you are sufficiently prepared as an organisation. This includes various analysis and priorization of your technical assets, definition of clearly defined playbooks and a documented overview of responsibilities. And do not forget to exercise these plans on a regular basis.
