DescrizioneLascereste mai aperta la porta di casa? Probabilmente no.Oggi le nostre abitazioni e i nostri uffici hanno diverse porte di accesso. Ci sono porte fisiche e porte digitali.Se per tutelarci dall’accesso indesiderato da estranei mettiamo una serratura sulla porta della nostra abitazione, la stessa cosa andrebbe fatta anche sulla porta informatica che apre la nostra casa al mondo di internet!Il firewall è uno strumento di controllo accessi che funziona esattamente come le porte “anti-incendio” che troviamo nei locali pubblici. Questo dispositivo ha la peculiarità di non permettere il passaggio dall’esterno verso l’interno, ma consente di uscire dall’interno verso l’esterno.In genere è installato subito dopo il router che offre la connessione a internet e con il quale s’interfaccia per poterne setacciare e bloccare eventuali intrusioni dall’esterno. Un esempio semplice semplice come piace a te? Bene! Immaginiamo che il router sia una cascata da cui fuoriesce un getto d’acqua (la connettività). Volendo filtrare l’acqua per assicurarci che non ci siano impurità, dovremmo mettere un setaccio a valle della cascata. Questo setaccio è il firewall.Esempio bislacco, ma sempre molto efficace. Il firewall, quindi è una sorta di porta “taglia-fuoco” con setaccio annesso, che impedisce intrusioni non desiderate e al contempo ha la possibilità di filtrare il contenuto che passa attraverso di esso.Ma quanti tipi di Firewall esistono? in cosa si differenziano? Perché mi serve conoscerli meglio?Questo corso ti darà tutte le risposte a queste domande e...a tante altre ancora!A chi è rivolto questo corso:Privati o titolari di piccole e medie imprese che vogliono conoscere meglio il mondo informatico usando parole chiare e di uso comune (senza troppi tecnicismi)Mostra di piùMostra meno

Do Udemy courses expire?

No, once you enroll, you will have lifetime access to the course. You can complete the course on your schedule.

Why are the Udemy instructors giving away free Udemy Coupons?

Every instructor has worked for hours on each of their courses. As new courses get launched, the instructors have no way to get their course in front of an audience to get some feedback. So, instructors share free coupons for their courses to get feedback from the students. We attheprogrammingbuddy.club work with these instructors to get their courses available to our buddies.

Is Udemy safe to use?

Yes, payments on Udemy are safe. It is no different than paying for other services on an application or website and inputting your payment information before receiving your goods. Just be sure to keep your account secure, do not share your udemy accounts.

Can Udemy courses get you a job?

Earning a skill is more valuable than earning a job these days. Skills are your most valuable asset. They can help you qualify for jobs you want and get promoted to more advanced positions within your organization. Unfortunately, it is difficult for many people to balance taking courses with work and family obligations. We have had many students, who have taken just Udemy courses, started a job as well as started freelancing with the skills they have learned.
