A promising approach to improved pa
A promising approach to improved password security is a proactive password
checker. In this scheme, a user is allowed to select his or her own password. However,
at the time of selection, the system checks to see if the password is allowable
and, if not, rejects it. Such checkers are based on the philosophy that, with sufficient
guidance from the system, users can select memorable passwords from a fairly
large password space that are not likely to be guessed in a dictionary attack.
The trick with a proactive password checker is to strike a balance between
user acceptability and strength. If the system rejects too many passwords, users will
complain that it is too hard to select a password. If the system uses some simple
algorithm to define what is acceptable, this provides guidance to password crackers
to refine their guessing technique. In the remainder of this subsection, we look at
possible approaches to proactive password checking.
RULE ENFORCEMENT The first approach is a simple system for rule enforcement.
For example, the following rules could be enforced:
• All passwords must be at least eight characters long.
• In the first eight characters, the passwords must include at least one each of
uppercase, lowercase, numeric digits, and punctuation marks.

Pendekatan yang menjanjikan untuk password peningkatan keamanan yang proaktif passwordchecker. Dalam skema ini, pengguna diperbolehkan untuk memilih kata sandi sendiri. Namun,pada saat seleksi, sistem cek untuk melihat apakah password diijinkandan, jika tidak, menolak itu. Checkers tersebut didasarkan pada filosofi bahwa, dengan cukupbimbingan dari sistem, pengguna dapat memilih sandi yang mengesankan dari cukupsandi besar ruang yang tidak cenderung ditebak dalam serangan Kamus.Caranya dengan proaktif password checker adalah untuk menyerang keseimbangan antarapengguna penerimaan dan kekuatan. Jika sistem menolak terlalu banyak password, pengguna akanmengeluh terlalu sulit untuk memilih kata sandi. Jika sistem menggunakan beberapa sederhanaalgoritma untuk menentukan apa diterima, ini menyediakan bimbingan sampai password scanneruntuk menyempurnakan teknik mereka menebak. Dalam sisa seksi ini, kita melihatmungkin pendekatan proaktif sandi memeriksa.ATURAN PENEGAKAN pendekatan pertama adalah sistem sederhana untuk penegakan aturan.Misalnya, aturan berikut dapat dilaksanakan:• Semua password harus setidaknya delapan karakter lama.• Di pertama delapan karakter, password harus menyertakan minimal satu setiapdigit huruf besar, huruf kecil, angka, dan tanda baca.
