Crittografia dei dati

Definizione

La crittografia dei dati è un tipo di processo di sicurezza che converte i dati da un formato leggibile, chiamato testo in chiaro, in una forma codificata e illeggibile, chiamata testo cifrato.

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.

Che cos’è la crittografia?

La crittografia è una misura di sicurezza che trasforma i dati leggibili (dati in chiaro) in un formato illeggibile utilizzando una chiave di crittografia unica (e privata). La crittografia rende i dati aziendali illeggibili e privi di valore per i criminali informatici che non hanno accesso alla chiave utilizzata per crittografare i dati.

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.

Che cos’è la crittografia e come funziona?

On the surface, encryption is a simple approach to a complex problem and is an essential element in data protection and di ripristino di emergenza. La crittografia aggiunge un livello necessario di protezione rendendo illeggibili le informazioni aziendali di valore, a meno che non vengano sbloccate con una chiave di crittografia appropriata. Senza l’accesso a questa chiave di crittografia univoca, i soggetti non autorizzati che ottengono l’accesso ai dati non hanno alcun modo di decifrarli o sfruttarli.

Gli aspetti principali della crittografia includono:

• 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 contrastare in modo proattivo il rischio di potenziali attacchi.
• 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.

Perché la crittografia è importante?

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

Le password complesse degli utenti non rappresentano più una forma efficace di protezione e vengono spesso sottratte e vendute a scopo di lucro.

Senza un’adeguata crittografia, le aziende rischiano di cadere vittime di attacchi, perdere dati e subire interruzioni dell’attività. Con strumenti adeguati di protezione e crittografia dei dati, le aziende possono garantire che i propri dati siano al sicuro, recuperabili e al riparo da mani indiscrete.

Vantaggi della crittografia

I dati e le applicazioni digitali sono i motori della crescita aziendale. Proteggere i dati relativi ai carichi di lavoro critici per l’azienda da potenziali perdite o furti è fondamentale per la sopravvivenza dell’azienda. La crittografia è un elemento fondamentale nella lotta alle minacce informatiche e svolge un ruolo significativo nella protezione dei dati, tra cui:

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.

Casi d’uso comuni della crittografia

Le organizzazioni di tutte le dimensioni necessitano di protezione dei dati. La crittografia svolge un ruolo fondamentale in queste soluzioni e contribuisce in modo significativo a proteggere i dati aziendali:

• 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.
