Criptografia de dados

Definição

A criptografia de dados é um tipo de processo de segurança que converte dados de um formato legível, chamado texto simples, em uma forma codificada e ilegível, chamada texto cifrado.

Encryption effectively scrambles usable data into a unique, random string of bits – rendering it undecipherable.

Decrypting data  requires access to a private encryption key, which decodes and unscrambles the encrypted dataset.

O que é criptografia?

A criptografia é uma medida de segurança que transforma dados legíveis (dados em claro) em um formato ilegível usando uma chave de criptografia única (e privada). A criptografia torna os dados empresariais ilegíveis e sem valor para os cibercriminosos que não têm acesso à chave usada para criptografar os dados.

Organizations that rely on plaintext format when storing or transmitting data have an increased risk of valuable business data and assets becoming compromised or falling into the wrong hands. Another danger that accompanies data theft is the possibility of public exposure of the victim’s private data.

Encryption provides an extra layer of security and helps organizations insulate their data, wherever it lives. Data protection solutions offer advanced encryption for both data at rest and in flight. In addition to encryption, cloud-based solutions can also isolate data copies in air-gapped, immutable locations. This ensures that data backups are unreadable and housed in immutable locations outside an organization’s network – keeping them out of reach from bad actors.

O que é criptografia e como ela funciona?

On the surface, encryption is a simple approach to a complex problem and is an essential element in data protection and Recovery de desastres. A criptografia adiciona uma camada necessária de proteção, tornando informações comerciais valiosas ilegíveis, a menos que sejam desbloqueadas com uma chave de criptografia adequada. Sem acesso a essa chave de criptografia exclusiva, pessoas não autorizadas que obtiverem acesso aos dados não terão como decifrá-los ou explorá-los.

Os principais aspectos da criptografia incluem:

• Robust security posture. Adopt an edge-to-cloud security posture that protects the edge, the data centers and the cloud properties. Empower IT to monitor the state of the environment’s security, manage access, encrypt data and combater proativamente o risco de possíveis ataques.
• Encryption. Organizations must establish strict policies for encrypting everything, especially data in flight, data at rest, and when possible, data in use. A unique encryption key is required to scramble data initiating the encryption process. Encryption is not a luxury and is widely available for IT to incorporate in data protection policies. There are two primary types of encryption keys: public and private. Most cloud providers offer rock-solid encryption and key management for the multi-tenant public cloud environments.
• Decryption. Using the unique encryption key, one can decrypt data, turning scrambled data back into a readable plaintext format. Encryption and decryption are commonly used in our day to day lives as many applications silently encrypt messages, data, and files without intervention from users.
• Key management. Like passwords, encryption keys need to be protected with restricted access. Some solutions maintain and protect encryption as part of their offerings. For solutions that allow customers to bring their own keys (BYOK), key management tools often sophisticated cryptography for safeguarding.
•  Prevention. Implement robust, zero-trust access controls and keep all antivirus apps up to date. Companies can avoid most of the potential risks by keeping unauthorized parties out of their environments at the first contact with the network.
• Proactive education. Cybercriminals use phishing and social engineering to penetrate the intended targets. Enterprises should routinely train and educate employees on the nature and the dangers of cyberattacks and the vital role they play in protecting valuable digital assets.

Por que a criptografia é importante?

The number of malicious cyberattacks incidents is on the rise, driven by  work from home (“WFM”) and distance learning vulnerabilities.

Senhas complexas de usuários não são mais uma forma eficaz de proteção e, muitas vezes, são roubadas e vendidas com fins lucrativos.

Sem criptografia adequada, é mais provável que as empresas sejam vítimas de ataques, percam dados e sofram interrupções nos negócios. Com ferramentas adequadas de proteção e criptografia de dados, as empresas podem manter seus dados efetivamente seguros, recuperáveis e fora das mãos erradas.

Benefícios da criptografia

Dados e aplicativos digitais são os motores do crescimento empresarial. Proteger os dados de cargas de trabalho críticas para os negócios contra possíveis perdas ou roubos é vital para a sobrevivência da empresa. A criptografia é fundamental no combate às ameaças cibernéticas e desempenha um papel significativo na proteção de dados, incluindo:

Mitigating attacks. Encryption’s primary goal is to prevent unauthorized parties from accessing proprietary data. Encrypted data is of no value to cybercriminals seeking to sell or publicly expose the stolen data – as it cannot be read, exploited or monetized. Without access to unique and private access keys, valuable business data is unreadable, and acts as a deterrent for cybercriminals.

Diminishing risk. Solutions with rigorous Encryption capabilities remove the prospect of negative exposure. While Encryption helps thwart the attempts of bad actors, it also narrows the window of liability when maintaining, managing, and storing sensitive information and data.

Lowering costs. The cost of protection pales compared to the costs of a business shutdown and potential customer data loss. Businesses should err on the side of proactive safety and adopt data protection solutions with robust encryption policies, regardless of their storage destination.

Casos de uso comuns para criptografia

Organizações de todos os tamanhos precisam de proteção de dados. A criptografia desempenha um papel vital nessas soluções e contribui significativamente para a segurança dos dados empresariais:

• Data protection. Without proper protection, data remains susceptible to potential loss and corruption. Encryption preserves the integrity of your data and usable backup copies that you alone can access with your protected encryption keys.
• Business continuity. With encryption software, businesses can protect all of their data and configurations needed to bring business back to life following unpredictable disruptions. Encrypted data is of no use to cybercriminals and may serve as a deterrent against future attacks.
• Disaster recovery. It is accepted that all businesses and IT environments may face disruptive encryption events that could cause data loss, corruption, or disrupted IT operations. Putting a robust encryption strategy in place reduces the risks associated with ill-intended cyberthreats and data theft.
